Nah ... I can stick to the topic of pulsars.
Electrical engineer Donald Scott says the phenomenon that gives pulsars their name (rapidly pulsed radio signals) "is produced electrically (much like a radio station)." He says "In the plasma that surrounds a star (or planet) there are conducting paths whose sizes and shapes are controlled by the magnetic field structure of the body. Those conducting paths are giant electrical transmission lines and can be analyzed as such. Depending on the electrical properties of what is connected to the ends of electrical transmission lines, it is possible for pulses of current and voltage (and therefore power) to oscillate back and forth from one end to the other. The ends can both be on the same object (as occurs on Earth) or one end might be on one member of a closely spaced binary pair of stars and the other end on the other member of the pair similar to the "flux tube" connecting Jupiter and its inner moon, Io." Scott goes on to note that in 1995 several super computer simulations were performed on a transmission line system model with properties believed to be those of a pulsar atmosphere and the results matched seventeen different observed emission properties.
The 1995 analysis he refers to is "Radiation Properties of Pulsar Magnetospheres: Observation, Theory, and Experiment" by Kevin Healy and Anthony Peratt (http://public.lanl.gov/alp/plasma/downloads/HealyPeratt1995.pdf ). Healy and Peratt concluded, “Our results support the ‘planetary magnetosphere’ view, where the extent of the magnetosphere, not emission points on a rotating surface, determines the pulsar emission. In other words, we do not require a hypothetical super-condensed object to form a pulsar. A normal stellar remnant undergoing periodic discharges will suffice. Plasma cosmology has the virtue of not requiring neutron stars or black holes (BAC - or quark stars as some observations suggest to the mainstream) to explain compact sources of radiation."
Furthermore, the jets coming from some pulsars might be explained thus: http://www.thunderbolts.info/tpod/2004/arch/040920pulsar.htm ... rather than relying on a host of gnomes.
Because of the losses in the dielectric media and in synchrotron emission, the periodicity of the propagating pulses increases. However the experiment dramatically showed that there are glitches, the flow of electron flux across the magnetosphere, can shorten the line and concomitantly the period. The fractional frequency stability scaling versus measurements interval up to about 30,000,000 s for pulsars is nearly identical to that for trapped-ion clocks. This supports the pulsar surface-magnetosphere relativistic double layer model; itself a trapped ion mechanism [.....]
Both simulation and experiment suggest that micro-pulses and sub-pulses are produced by particle-wave interactions in non-uniform plasma eradiated by the electromagnetic wave. This effect is produced when the magnetically insulated voltage pulse reaches the pulsar surface. Because of the curvature, magnetic insulation is lost and plasma flows across this region. This tends to create a resonating or modulating component to the proper current pulse [...]
The source of the radiation energy may not be contained within the pulsar, but may instead derive from either the pulsars interaction with its environment or by energy delivered by an external circuit (Hannes Alfvén 1981).[2] This hypothesis is consistent with both the long term memory effect of the time averaged pulse and the occurrence of nulling, when no sub-pulses are observed. As noted earlier, our results support the 'planetary magnetosphere' view (Michael 1982) where the extent of the magnetosphere, not emission points on a rotating surface, determines the pulsar emission.
"Hubble Space Telescope Observations Reveal Coolest and Oldest White Dwarf Stars in the Galaxy: "Using the Hubble Space Telescope, astronomers at the Naval Research Laboratory (NRL) have detected five optical companion stars orbiting millisecond pulsars. Only two other such systems are known. Three of the companions are among the coolest and oldest white dwarf stars known."
A small knot of bright emission located only 1500 AU (1500 times the distance from the Earth to the Sun) from the pulsar. This knot has gone undetected up until now because even at the best ground-based resolution it is lost in the glare of the adjacent pulsar. The knot and the pulsar line up with the direction of a jet of X-ray emission. A second discovery is that in the direction opposite the knot, the Crab pulsar is capped by a ring-like 'halo' of emission tipped at about 20 degrees to our line of sight. In this geometry the polar jet flows right through the center of the halo.

More 'plasma cosmology' woo
Got any numbers to go with that PC woo BAC? Like estimates of the magnetic field strength? Or an explanation of the neutrino emission? Or a quantitative match to the observed brightnesses (fluxes, luminosities)? Or a SED (spectral energy distribution) or two?
*Waits for BaC or Zeuzzz to post something about redshift anomalies*
Idiocy and creativity at the same time; cranks are like that.
A good rule of thumb I have found, if someone calls something woo, it likely means that theres something to it, as no scientific reason has been given, just an offhand accusation of woo-ivity.
*Waits for BaC or Zeuzzz to post something about redshift anomalies*Ask and ye shall receive...
So how many mutually incompatible 'plasma cosmology' accounts of pulsars are we up to now?Well pointed out BAC. I think that all of this is a far more plasuible explantion for pulsars than the current one, and I hadn't thought of the possible link between this and the Jupiter-Io connection before, but that makes a lot of sense.
... snip ...
Well, why not actually go and read some papers on this?And this discovery is way cool, I had heard of pulsars spinning at 716 Hertz before (716 times per second, ref; Astronomers Discover Fastest-Spinning Pulsar), but this one blows it out of the water at 2150 rotations per second. The question surely has to arise; Is this speed really tenable?, or are the pulses we detect from them due to something else? This sort of speed was certainly not anticipated when the original interpretation of pulsars was proposed.
And your opinion is based on what, exactly?... snip ...
When Neutron stars were first discovered it was thought that they rotated rapidly - like lighthouses. But I find this very unlikely now, even when the observed rate of "rotation" got up to about once per second for certain pulsars, despite their having masses exceeding that of the sun, the old official explanation became largely untenable in my opinion.
Well, now we have three mutually incompatible 'plasma cosmology' ideas ... and some indirect evidence (you listening JEROME?) that Zeuzzz is Michael Mozina!This is where the concept of the "Neutron star" was invented. It was proposed that only such a dense material could make up a star that could stand those rotation speeds. (Some nuclear chemists have noted that current explanations for Neutron Stars violate the Island of Stability, as it is now known that neutrons can not be packed that close together without spontaneously undergoing radioactive transformations. Despite this fact, most astronomers remain confident that the gravity of neutron stars is strong enough to alter the fundamental observations of nuclear chemistry significantly on the atomic scale, despite gravities role at this scale still being a bit of a mystery (ref: The Nuclear Cycle that Powers the Stars Journal of Fusion Energy, 2006) . This quite recent empirical observation even challenges the conventional assumption that stars are powered by H-fusion, but that’s for another thread in the future, not here, I feel. ref, ref)
Which ones?... snip ...
Another one that offers further proof of this is one of the nearest to us (is it the nearest actually???), the "Crab Nebula", which is currently thought to have a Neutron Star at its centre, CM Tauri. The frequency of repetition of the pulsar's output is 30 pulses per second. The length of each flash, however, is approximately 1/1000 sec, just one millisecond. This lead Plasma cosmologists
(emphasis added)... snip ...
Another thing that I find fascinating about pulsars is that it is well known that the pulses are considered some of the most accurate clocks in the universe, of relative accuracy of 10-15 And here on earth the most accurate clocks are Ion clock mechanisms; which is the exact mechanism that Peratt and Plasma Cosmologists propose is occurring in Pulsars, ie, ions periodically building up and discharging in the stellar circuit.
... snip ...
And of course, no logic of false dichotomy operating here.And to counter the usual "We all ready know nearly everything about pulsars, this is all plasma cosmology woo-hoo-poo" response I can anticipate; many details of pulsars are are still poorly understood, such as:
... snip ...
Indeed ...This long list of uncertainties with pulsar theory certainly adds room for the possibility of the plasma cosmology interpretation turning out correct. And I feel this is one of the areas that PC excels at explaining.
Ah yes ...If you look at pictures of the pulsar in the Crab Nebula, it certainly takes the morphology of a unipolar inductor, with a central current filament and a rotating EM field of plasma surrounding it;
... snip ...
Hmm ...Come on dude, someone with your capability can surely add something constructive here to the quite considerabale amount of information in my post. And its not as if its my theory, I'm just relaying the work of other scientists. This comment is almost as helpful as the one comment you contributed to the "Plasma cosmology - woo or not" thread, by just saying, "It is the very definition of woo", and leaving it at that. Well, do you have any reason for this supposition? or not?
... snip ...
So how many mutually incompatible 'plasma cosmology' accounts of pulsars are we up to now?
I count at least two; before this post is over, there may be more ...
Well, why not actually go and read some papers on this?
(material on this for interested readers to follow, in a later post)
And your opinion is based on what, exactly?
Well, now we have three mutually incompatible 'plasma cosmology' ideas ... and some indirect evidence (you listening JEROME?) that Zeuzzz is Michael Mozina!
Oh, and yet more inconsistencies between 'if it hasn't been observed in the lab, it doesn't exist!' and 'here's something plasma cosmologists accept'.
Which ones?
Michael Mozina?
Wallace Thornhill?
Don Scott?
Eric Lerner?
Anthony Peratt?
Dr. László Körtvélyessy?
Ian Tresman?
Dwardu Cardona?
(emphasis added)
Now that I've quoted your post, you can't go edit it.
So, when I (or someone else) gets around to going through that Healy and Peratt paper, and discovers that there is, shall we say, a discrepancy ...
And of course, no logic of false dichotomy operating here.
Further, all these - and more! - have been explained in great and glorious detail in the Healy and Peratt paper (or is it the Dr. László Körtvélyessy model? Or the 'Sun has a solid iron surface' model? I get confused over which of the mutually inconsistent explanations is the *true* plasma cosmology one).
Indeed ...
Apart from the trivial little detail of there being at least two (three?) mutually inconsistent 'plasma cosmology' explanations, and no papers which actually go through the tiresome bother of providing a consistent, quantitative account of all of the above, and ...
Ah yes ...
The devastatingly insightful scientific method called 'look at this picture!'
Have you done any calculations for this? I would like to see them. Or is this just argument from incredulity.When Neutron stars were first discovered it was thought that they rotated rapidly - like lighthouses. But I find this very unlikely now, even when the observed rate of "rotation" got up to about once per second for certain pulsars, despite their having masses exceeding that of the sun, the old official explanation became largely untenable in my opinion.
It violates the island of stability? What do you mean?This is where the concept of the "Neutron star" was invented. It was proposed that only such a dense material could make up a star that could stand those rotation speeds. (Some nuclear chemists have noted that current explanations for Neutron Stars violate the Island of Stability, as it is now known that neutrons can not be packed that close together without spontaneously undergoing radioactive transformations.
There is good reason you know. Like the lack of white dwarf stars above 1.4 solar masses. And type 1a supernovas. How does your pet theory explain these?Despite this fact, most astronomers remain confident that the gravity of neutron stars is strong enough to alter the fundamental observations of nuclear chemistry significantly on the atomic scale, despite gravities role at this scale still being a bit of a mystery
When I've got time I'll go through this. Can I just ask... are you really willing to support a theory suggesting there is a neutron star in the centre of the Sun?(ref: The Nuclear Cycle that Powers the Stars Journal of Fusion Energy, 2006) .
This quite recent empirical observation even challenges the conventional assumption that stars are powered by H-fusion, but that’s for another thread in the future, not here, I feel.

1) Their magnetosphere structures are a bit of a mystery (bandaged dipoles being one theory out of many, and, I think, the most popular current one; http://www.springerlink.com/content/l27044q5g2148051/)
2) The work function of their polar caps, has been observed to vanish in the presence of a pair plasma corona, generated by electron bombardment
3) the origin of the extreme brightness temparature of their coherent radio pulses, reaching 1028±2K in the peaks
4) Radiation at all higher than radio frequencies not explained by current theories
5) high degrees of polarization (which i think has been observed both circular and linear)
6) intensity fluctuations from pulse to pulse, who's histograms fall into some five different categories (briefly addressed in Peratts publication)
7) 3-d bean shapes, or antenna patterns, composed of huge numbers of narrowed spikes, with net bean fraction ~1
8) The modes of formation (currently via SN explosion in all cases, even including the ms pulsars!)
9) modes of extinction (via suffocation?, or some other not fully known mechanism) A question remains on whether the ms pulsars are 'recycled', ie, spun by accretion, just born fast, or from the Van Allen hypothesis (which would explain why their magnetic fields are always so high, which implies a relation between the speed of rotation and the magnetic field, something lacking from conventional theories; http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4287019 [the plasma cosmology interpretation of the three]
10) occasional Giant pulses radio emission (these events, surprisingly, have actually been attributed to electric discharges already, see; http://www.mssl.ucl.ac.uk/~sz/Conference_files/pres/kuzmin.pdf "Giant pulses radio emission is generated in the electric discharge taking place due to the magnetic reconnection of field lines connecting the opposite magnetic poles” [of course though, Alfvens electrical double layer, or current disruption model, is preferred to the "magnetic reconnection" idea of "merging lines" by most PC proponents]
Even their spindown ages (tsd := P/2P) have been occasionally questioned as upper bounds on their true ages. The spindown obeys;
[latex](p^{2})^{.}=\frac{16\pi^{2}D^2}{3c^{3}I}[/latex]
for a transverse magnetic dipole moment D, (≈ 1031Gcm3), and a moment of inertia I ≈ 1045gcm2. The positive initial period ( P(t0) ) is uncertain, and so renders the rest of the relationship questionable.
... snip ...
Correct.Stable nuclei of the lighter elements contain approximately equal numbers of neutrons and protons, a neutron/proton ratio of 1.
Yes, generally. Though there are exceptions.The heavier nuclei contain a few more neutrons than protons, but the limit seems to be 1.5 neutrons per proton. Nuclei that differ significantly from this ratio spontaneosly undergo radioactive transformations that tend to bring their compositions into or closer to this ratio.
Well if you had a nucleus and you just kept adding neutrons on to it then it would, fission, alpha decay or the neutrons would just drop off. But this isn't what happens in a neutron star. So this argument doesn't apply.This should mean that the Neutronium that Neutron stars are thought to be constituted of can not exist for long enough to form the current stable structures, or, this reaction could be resonsible for the huge amount of energy we see from these types of objects, whether at the centre of the galaxy or a typical Neutron star candidate.
You're thinking of the "valley of stability", not the "island of stability". I'm still not sure why you're using the word "violating" though.Nuclear chemistry is not really my strong point, so i'm taking their word for this... and I admit I may have misrepresented that part about the island of stability, i'll leave that up for you to decide... http://www.physorg.com/news8658.html
That's because its nonsense. And you mean neutrons or nucleons not nuclides.Not so sure about that certain aspect, but the repulsion between these nuclides does seem to contradict many things in current models.
I have a vague recollection of reading a list much like this elsewhere - if this is other than entirely your own work, would you mind telling us what your source(s) are Zeuzzz?
I'm also curious to know what your source is for the spindown expression ... it is (I guess) from someone or other's model, no doubt published in some paper somewhere (perhaps repeated now in some standard astrophysics text too).
May one enquire as to what criteria you would use to decide who such users are?Oh, I also recommend filtering out users who engage in trolling, insults and straw dogs. Life is too short to waste any of it.
The double pulsar system PSR J0737-3039A/B is unique in that both neutron stars are detectable as radio pulsars. They are also known to have much higher mean orbital velocities and accelerations than those of other binary pulsars. The system is therefore a good candidate for testing Einstein's theory of general relativity and alternative theories of gravity in the strong-field regime. We report on precision timing observations taken over the 2.5 years since its discovery and present four independent strong-field tests of general relativity. These tests use the theory-independent mass ratio of the two stars. By measuring relativistic corrections to the Keplerian description of the orbital motion, we find that the ``post-Keplerian'' parameter s agrees with the value predicted by general relativity within an uncertainty of 0.05%, the most precise test yet obtained. We also show that the transverse velocity of the system's center of mass is extremely small. Combined with the system's location near the Sun, this result suggests that future tests of gravitational theories with the double pulsar will supersede the best current solar system tests. It also implies that the second-born pulsar may not have formed through the core collapse of a helium star, as is usually assumed.
May one enquire as to what criteria you would use to decide who such users are?
Ones who say:
Such terrible logic and huge fallacies. (without saying what, or why)?
Yet another fallacy! Marvelous. (without saying why)?
Yet another illogical assumption! (without saying what, why, how, or ...)?
Not true. (without saying why, or how, or ...)?
That claim is utter nonsense (with no explanation)?
To what extent would you say those who write such things are engaging in "trolling, insults and straw dogs"?
May I suggest following list?

May be I missed some,but these are bit persistent...
It seems there are two different aspects of pulsars/magnetars/neutron stars being questioned/discussed in this thread:
* whether there are dense objects with masses ~1 sol, that are (somehow) associated with gamma/x-ray/optical/radio pulses and/or very characteristic nebulae (i.e. diffuse sources)
* what the mechanisms are which give rise to the observed pulses.
There's also been the question of how the emission in the diffuse nebulae arises.
Let's take the 'dense, massive objects' first.
In 1993, Hulse and Taylor were jointly awarded the Nobel Prize for physics, for the discovery of the 'Hulse-Taylor' pulsar, and analysis of observations of it showing that it is in a binary whose mutual orbits are decaying at a rate consistent with Einstein's theory of General Relativity (GR), due to the emission of gravitational wave radiation. Here is the Nobel committee's announcement, here is Hulse's Nobel lecture, here is Taylor's, and when the site comes back up, I'll post the section in Clifford Will's latest "The Confrontation between General Relativity and Experiment" that discusses this (and similar) object.
In 2003 a double pulsar was discovered - two pulsars in orbit around each other. This system has permitted much more rigorous testing of GR than the Hulse-Taylor pulsar could - this Jodrell Bank PR gives a brief description, as well as links to some papers.

Abstract:
Terrestrial planets in close orbits around magnetic white dwarf stars are potential electron-cyclotron maser sources, by analogy to planetary radio emissions generated from the electrodynamic interaction between Jupiter and the Galilean moons. We present predictions of radio flux densities and the number of detectable white-dwarf/terrestrial-planet systems, and discuss a scenario for their formation.
This ATNF* introduction gives a good, if brief, account of pulsars (it also has a link to a more advanced tutorial).
Until the 'living reviews' website comes back up, the 2006 paper Tests of General Relativity from Timing the Double Pulsar will have to do to summarise just how far the study of pulsars has come in terms of putting GR through its paces; here's the abstract (emphasis added):
* Australian Telescope National Facility - one of the primary 'pulsar hunters'.
If anyone is interested in learning, in more detail, how the many years of astronomical observations, across the entire electromagnetic spectrum, have been interpreted as 'here be dense, massive objects called neutron stars', please ask (and I'll be happy to take a shot at explaining).
Next: pulsars/magnetars/neutron stars as plasma physics laboratories.
Both simulation and experiment suggest that micro-pulses and sub-pulses are produced by particle-wave interactions in non-uniform plasma eradiated by the electromagnetic wave. This effect is produced when the magnetically insulated voltage pulse reaches the pulsar surface. Because of the curvature, magnetic insulation is lost and plasma flows across this region.[....]
However, further observations led by astronomers at MSSL found that two of the distingushing characteristics of polars - polarised optical light and optical emission lines - were absent Ramsay et al 2002). This paper proposes several other scenarios for RX J1914+24. These include a double degenerate Algol system (also proposed independently by Marsh & Steeghs 2002), a neutron star-white dwarf pair and a unipolar-inductor model (or electric star model). The latter model would represent a third form of stellar energy after nuclear and accretion power. It is described more fully in Wu et al 2002) .
This proposal may seem rather far-fetched. However, we do know that a similar effect has been observed on Jupiter where its satellite's rotate round the magnetic field of Jupiter causing electrical currents to be driven. These are deposited in the Jovian atmosphere causing bright streaks which were imaged using the Hubble Space Telescope:
![]()
(Satellite Footprints Seen in Jupiter Aurora)
This image shows both the aurora on Jupiter (caused by the same effect as the Northern lights we observe on Earth) and also the footpoints of three of Jupiters satellites. Each footprint is represented by a bright dot. Io's footprint is at far left; Ganymede's is just below and to the right of center; and Europa's is to the right of Ganymede's signature.
In the case of RX J1914+24, the currents which are generated are much greater than that in Jupiter since the secondary white dwarf is rotating around the primary white dwarf on a much shorter timescale and its mass is much greater than that of Jupiter's satellites. The diagram below shows how the energy is liberated on the magnetic white dwarf:

Satellite Footprints Seen in Jupiter Aurora.
This model can explain all the observed characteristics of RX J1914+24. [....]
Timing measurements of periodic X-ray pulses from two ultrashort-period double degenerate binaries, RX J1914+24 and RX J0806+15, show that the rates of change of their orbital periods are consistent with gravitational radiation losses. This contradicts the predictions of models which invoke mass transfer between the two white dwarfs. The X-ray emission is, therefore, unlikely to be powered by accretion processes. The unipolar inductor model explains the source of X-ray emission as electrical dissipation at the base of a flux tube, which connects the magnetic white dwarf to its companion. This model is most consistent with the observed X-ray pulse properties. A similar current system exists in the Jupiter-Io system, where a mildly relativistic electron current produces an auroral footprint at the base of the Io flux tube and highly polarized beamed radio emission by means of the electron cyclotron maser mechanism. Detection of radio emission from RX J1914+24 and RX J0806+15 would thus provide further support for the unipolar inductor model. We present theoretical predictions, based on a loss-cone-driven electron cyclotron maser model, of radio fluxes from systems with parameters similar to RX J1914+24 and RX J0806+15.
Naval Research: The Sun - Inflows
Astronomers spend a lot of time studying what flows away from the Sun, such as supercharged particles, hot gases, light, heat, and other types of energy. They want to know what is coming toward the Earth so that we can learn how to protect our astronauts, satellites, and communications. Now scientists believe that by studying material that flows into the Sun, they can better understand what comes out of the Sun.
