A homogeneous nucleus for comet 67P/Churyumov– Gerasimenko from its gravity field is not about the first few meters of the surface that MUPUS-PEN sampled or the rest of his deluded highlights of the paper and his usual insane comments.

Is near-surface ice the driver of dust activity on 67P/Churyumov-Gerasimenko

Read 254 items of ignorance, delusion and lies dating from 29 August 2016 to 23 August 2017 (maybe hundreds more in the last 8 years!) for his previous delusions and lies about dust activity.

According to your delusions, the only bodies that can be comets are ones coming from the other system to the inner system. Main-belt comets cannot exist in your ignorant and deluded dogma !

On the other hand, there is the real world. In the real world ices sublimate within the snow line (about 5 AU). Asteroids may have ices. These ices can be exposed making some main-belt asteroids into temporary comets.

Asteroid–comet continuum objects in the solar system
Henry H. Hsieh1,2

Quote:
4. Conclusion In summary, the population of small bodies in our solar system today, including both minor planets and classical comets, is far less well-delineated into distinct groups of objects than the classical paradigm might have led one to believe in the past. These objects instead appear to occupy a continuum spanning the full range of observational, physical and dynamical properties classically attributed solely either to asteroids or comets. We now know of currently actively sublimating main-belt objects that could have originated either in the asteroid belt or in the outer solar system, and objects displaying comet-like activity that may have no volatile ice content whatsoever. We have found objects composed of inner-asteroid-belt-like material on long-period comet-like orbits, and active objects on comet-like orbits that may in fact originate from the asteroid belt. We also now recognize that dormant comets may be found in both comet-like and un-comet-like orbits. The population of continuum objects is extraordinarily diverse, with each type of object holding the potential for revealing exciting new insights about our solar system due to their unique sets of overlapping comet- and asteroid-like properties. Given this complexity and the growing interest in addressing the many questions that it has raised thus far, it is likely that many more interesting findings await us in this rapidly developing field in the coming years.
So still interesting Dancing David, Reality Check ay!

Well maybe we can start at the start?

Mainstream get there assumption from models developed to try and explain observations.

Such as..
  1. the icy-glue model (Gombosi & Houpis 1986)
  2. the icy conglomerate model (Klinger et al. 1985)
  3. the fluffy aggregate model (Donn & Meakin 1989)
  4. the primordial rubble model (Weissman 1986)
  5. the layered pile model (Belton et al. 2007)
  6. The Sandbank model ( Raymond Lyttleton 1953)
All REQUIRE sublimation of frozen gases to try and explain observations.

So now after all the new data and observation we can rule out

the icy-glue model (Gombosi & Houpis 1986)
the fluffy aggregate model (Donn & Meakin 1989)
the primordial rubble model (Weissman 1986)
the layered pile model (Belton et al. 2007)
The Sandbank model ( Raymond Lyttleton 1953)

and the icy conglomerate model (Klinger et al. 1985), is on very shaky ground.

So that basically leaves the mainstream with NO MODEL to try and make sense of the data and observation.

So ad hoc explanations that are untestable rule the roost!

but the ELECTRIC COMET...

Solid as ROCK!!

Hybrid modelling of cometary plasma environments

If fact, how does that work inside the diamagnetic cavity?

Maybe you should read Cyril's paper, and then you would see that this paper is about:

Impact of photoionisation, charge exchange, and electron ionisation on bow shock and cometopause at 67P/Churyumov-Gerasimenko

So, methinks you are a few 1000 km in the wrong place.

But it is coupled via complex plasma phenomena, including I'd say double layers!

Or as you'd call 'em, plasma boundaries

As if in the dust is coupled all the way from the rock hard surface of the comet, all the way in a circuit way out too whoop whoop and back! The focus for the energy is the comet nucleus itself!

The bright spots are not ice but indeed the glow mode electric discharge machining of solid rock producing very fine dust composed on some comets as extremely high temperature minerals. Flash heated in a arc mode EDM, not seen on this low voltage outgassing comet. The bright spots also appear to be changing the surface as we watch.

These are confined into collimated 'jets' that we observe doing there thing.

But Hartley 2, had em stumped for water produced per surface area of nucleus...

If you are actually interested in the diamagnetic cavity then you should read Etienne Behar's paper The birth and growth of a solar wind cavity around a comet – Rosetta observations

I am still waiting on the first paper by the EC community!

Question Sol88: What is your prediction for the "water produced per surface area of nucleus"

Back to the subject of the thread: Questions with deafening silence emphasizing the complete uselessness of the comets are rocks delusion.
  1. 14 August 2017 Sol88: Comets are rocks so where did that rock come from?
  2. 18 August 2017 Sol88: What is your predicted composition of comets from their origins?
  3. 18 August 2017 Sol88: What is your predicted density of comets?
  4. 18 August 2017 Sol88: What is the measured density of comets?
  5. 18 August 2017 Sol88: State the physics that explains any density difference showing that the measurements are matched.
  6. 22 August 2017 Sol88: Why are all main-belt asteroids not comets according to your comet delusions?
  7. 22 August 2017 Sol88: Why are all asteroids with cometary obits not comets as in your comet delusions?
  8. 23 August 2017 Sol88: Why does comet dust not match planetary rock or asteroid composition?
  9. 23 August 2017 Sol88: What is your evidence that comets were blasted from planets such as the Earth?
28 August 2017 Sol88: What is your prediction for the "water produced per surface area of nucleus" on Hartley 2?

The mainstream model of sublimating ices has worked for the last 70 years. Your comet delusions as you know have been debunked since the day they were proposed by the existing data on comets.

I still dont get why Sol seems to equate density with hardness- just because something is hard, doesnt mean its dense, and vice versa

Oh and thankyou to tusenfem and the others for posting links to the various papers, its fascinating to see the progress on the various missions continuing long after the 'media' drops them

Exactly, dislocations in a lattice structure reduce density but can increase hardness.


https://en.wikipedia.org/wiki/Hardness

Quote:
By varying the presence of interstitial atoms and the density of dislocations, a particular metal's hardness can be controlled. Although seemingly counter-intuitive, as the density of dislocations increases, there are more intersections created and consequently more anchor points. Similarly, as more interstitial atoms are added, more pinning points that impede the movements of dislocations are formed. As a result, the more anchor points added, the harder the material will become.

From my metallurgy classes I recall the three primary crystalline structures for steel as Austenite, Pearlite and Martensite.

https://en.wikipedia.org/wiki/Austenite

https://en.wikipedia.org/wiki/Pearlite

https://en.wikipedia.org/wiki/Martensite

While austenite is denser martensite is significantly harder (can also be harder than pearlite), again due to the number of dislocations.

Quote:
One of the differences between the two phases is that martensite has a body-centered tetragonal (BCT) crystal structure, whereas austenite has a face-centered cubic (FCC) structure. The transition between these two structures requires very little thermal activation energy because it is a diffusionless transformation, which results in the subtle but rapid rearrangement of atomic positions, and has been known to occur even at cryogenic temperatures.[1] Martensite has a lower density than austenite, so that the martensitic transformation results in a relative change of volume.[4] Of considerably greater importance than the volume change is the shear strain which has a magnitude of about 0.26 and which determines the shape of the plates of martensite.[5]

Martensite is not shown in the equilibrium phase diagram of the iron-carbon system because it is not an equilibrium phase. Equilibrium phases form by slow cooling rates that allow sufficient time for diffusion, whereas martensite is usually formed by very high cooling rates. Since chemical processes (the attainment of equilibrium) accelerate at higher temperature, martensite is easily destroyed by the application of heat. This process is called tempering. In some alloys, the effect is reduced by adding elements such as tungsten that interfere with cementite nucleation, but, more often than not, the nucleation is allowed to proceed to relieve stresses. Since quenching can be difficult to control, many steels are quenched to produce an overabundance of martensite, then tempered to gradually reduce its concentration until the preferred structure for the intended application is achieved. The needle-like microstructure of martensite leads to brittle behavior of the material. Too much martensite leaves steel brittle; too little leaves it soft.


Quote:
The highest hardness of a pearlitic steel is 400 Brinell whereas martensite can achieve 700 Brinell.[2]
Austenitic Alloys run about 110 to 256 Brinell.

Similarly ice is less dense than water but harder, though that is due to the nature and rigidity of the lattice structure vs the degrees of freedom in the water phase. In contrast to the dislocations inherent in different lattice structures of steel noted above.

Yup, or it could also be rock, in fact bedrock!

Geomorphology of comet 67P/Churyumov–Gerasimenko Samuel P. D. Birch,1‹ Y. Tang,2 A. G. Hayes,1,2 R. L. Kirk,3 D. Bodewits,4 H. Campins,5 Y. Fernandez,5 R. de Freitas Bart,2 N. W. Kutsop,2 H. Sierks,6
J. M. Soderblom,7 S. W. Squyres1,2 and J-B. Vincent6,8


Quote:
ABSTRACT
We present a global geomorphological map of comet 67P/Churyumov–Gerasimenko (67P/C- G) using data acquired by the Rosetta Orbiter’s OSIRIS Narrow Angle Camera. The images used in our study were acquired between 2014 August and 2015 May, before 67P/C-G passed through perihelion. Imagery of the Southern hemisphere was included in our study, allowing us to compare the contrasting hemispheres of 67P/C-G in a single study. Our work also puts into greater context the morphologies studied in previous works, and also the morphologies observed on previously visited cometary nuclei. Relative to other nuclei, 67P/C-G appears most similar to 81P/Wild 2, with a topographically heterogeneous surface dominated by smooth-floored pits. Our mapping describes the landscapes of 67P/C-G when they were first observed by Rosetta, and our map can be used to detect changes in surface morphologies after its perihelion passage. Our mapping reveals strong latitudinal dependences for emplaced units and a highly heterogeneous surface. Layered bedrock units that represent the exposed nucleus of 67P/C-G are dominant at southern latitudes, while topographically smooth, dust covered regions dominate the Northern hemisphere. Equatorial latitudes are dominated by smooth terrain units that show evidence for flow structures. We observe no obvious differences between the comet’s two lobes, with the only longitudinal variations being the Imhotep and Hatmehit basins. These correlations suggest a strong seasonal forcing on the surface evolution of 67P/C- G, where materials are transported from the Southern hemisphere to Northern hemisphere basins over multiple orbital time-scales.
But yeah interesting about metal hardness

I don't get why they designed and lander to land on a comet, made as we KNOW of dust and ice, and not design the penetrator to penetrate highly porous 'ice' with some dust!

Complete FAIL! Unless they just proved comets are NOT made from ice and dust matrix

Which I think, from the abstract, is the correct terminology for a comet nucleus, comets are a ROCKY body!

So really the only question is if comets are rocks, rocky, well consolidated material, bedrock... take your pick. Then what are the implications for the solar nebula hypothesis?

Or as Reality check would like to know, 'where does the rock come from'?

Your citaion doesn't say "in fact bedrock" it refers to "Layered bedrock units...". a method of identifying different layers of stratified material.

https://www1.maine.gov/dacf/mgs/pubs...k/bed-read.htm

How exactly does the EC model the lithification of that "in fact bedrock"?

The dislocation and anchoring factors apply to hardness in general and have particular relevance for stratified materials. As those dislocation and anchoring elements can be an inherent result of the layering process.

A 'ice' lie.
Another lie because he does know about the MUPUS-PEN design and testing using the knowledge of comets in about 2001. MUPUS-PEN was designed to penetrate highly porous ice with some dust. What we found was highly porous sintered ice with some dust.
4 September 2017 Sol88: A couple of lies about the MUPUS-PEN design and testing that he has cited several times.

The question is whether you will ever stop mindlessly parrot your comet delusions (comets are rocks, etc.). The answer is obviously never because we have:
4 September 2017 Sol88: 8 years of denial of basic arithmetic (0.6 g/cc < 3.0 g/cc).

Emphasizing that the electric comet is not only insanely deluded but also completely useless is not smart.
Questions with deafening silence emphasizing the complete uselessness of the comets are rocks delusion.
  1. 14 August 2017 Sol88: Comets are rocks so where did that rock come from?
  2. 18 August 2017 Sol88: What is your predicted composition of comets from their origins?
  3. 18 August 2017 Sol88: What is your predicted density of comets?
  4. 18 August 2017 Sol88: What is the measured density of comets?
  5. 18 August 2017 Sol88: State the physics that explains any density difference showing that the measurements are matched.
  6. 22 August 2017 Sol88: Why are all main-belt asteroids not comets according to your comet delusions?
  7. 22 August 2017 Sol88: Why are all asteroids with cometary obits not comets as in your comet delusions?
  8. 23 August 2017 Sol88: Why does comet dust not match planetary rock or asteroid composition?
  9. 23 August 2017 Sol88: What is your evidence that comets were blasted from planets such as the Earth?
  10. 28 August 2017 Sol88: What is your prediction for the "water produced per surface area of nucleus" on Hartley 2?
Silence from you needs the question:
4 September 2017 Sol88: Are you not honest enough to acknowledge Thunderbolts comet origins?
If you are then cite it and say that you support it.

Electric comets still do not exist!

Astronomers aren't sure whether the minerals found in Stardust's comet samples formed near the Sun or around another star, though isotope scans are expected determine that for sure in upcoming tests, Brownlee said. Olivine, a mix of iron and magnesium that appears green on some Earth beaches, is one of the several surprising compounds found in the Wild 2 samples, he added.

Michael Zolensky, Stardust curator and a mission co-investigator at NASA's Johnson Space Center (JSC), said astronomers believed that a sort of material "zoning" occurred during the Solar System's formation.

According to the model, substances formed under hotter temperatures closer to the Sun, while colder materials - such as the gases that make up the giant planets - took root further out, he added.

But if Stardust's comet samples are found to be local to the Solar System, and not from some distant start, they'd suggest a sort of transportation system to fling particles formed near the Sun out past the orbit of Pluto and into the comet realm, researchers said.

"If this mixing is occurring, as suggested by these results, than how do you preserve any kind of zoning in the solar system," Zolenksy said. "It raises more mysteries."

Spitzer was one of the 80 or so telescopes trained on Comet 9P/Tempel 1 when it rammed into the 370-kilogram copper-tipped impactor sent into its path. A spectrometer on the telescope detected a mix of materials as they streamed off the comet, including crystallised silicates, clay and carbonates.

Clay and carbonates are thought to form in liquid water, which can only exist for long periods on the surface of planets or other objects no further from the Sun than Mars. But comets such as Tempel 1 are thought to have formed as smaller chunks of material smashed together around the orbit of Neptune – where any water would be in the form of ice.

“How did clay and carbonates form in frozen comets?” says Carey Lisse, an astronomer at the University of Maryland in College Park, US, who observed the impact with Spitzer. “We don’t know, but their presence may imply that the primordial solar system was thoroughly mixed together, allowing material formed near the Sun where water is liquid, and frozen material from out by Uranus and Neptune, to be included in the same body.”
Comet’s minerals hint at liquid water


But the new stuff

Insane repeating what has been already addressed in the last 8 years of the thread.
NASA's Stardust Comet Samples Contain Minerals Born in Fire
Stardust detected the expected non-planetary grains but his delusions demand planetary material.
The grains formed in the early solar system but his delusions demand grains formed today.
Some of the grains have minerals formed in the inner solar system ("Born in Fire") and were transported to the outer solar system to make up comets.

Comet’s minerals hint at liquid water
Liquid water as in ices melted by heat from the Sun - again in the early solar system !

GIADA: shining a light on the monitoring of the comet dust production from the nucleus of 67P/Churyumov Gerasimenko


Quote:
The measured masses and speeds of compact particles are in the range from 10−10 to 3.9 × 10−7 kg and from 0.3 to 12.2 ms−1, respectively.
So a bit rock like.

Quote:
The analysis of compact particle speeds versus cometocentric distance shows that in the dust acceleration region, the dust speed increases from 2.5 ± 0.8 ms−1 at 10 km to 4.3 ± 0.9 ms−1 at 30 km.
Accelerating? I hear you say...

But

Quote:
We were able to describe the evolution of the 3D dust distribution with respect to the distance from the comet and to identify the spatial distribution of different types of dust particles: uffy particles, that is, 0.2 to 2.5 mm porous aggregates of submicron grains (equivalent bulk density <1 kgm−3) and compact particles, ranging in size from 80 to 800 microns.
So really small and fluffy and able to clump together but still <1kgm-3.

Quote:
Monitoring the coma terminator dust environment, we give a rough estimate of the dust activity increase at decreasing heliocentric distance of roughly a factor of about 6 from 3.36 to 2.43 AU.
So really dusty too??

Quote:
The dust flux of submicron particles coming from the solar direction is three times higher than the one coming directly from the nucleus. The measured dust flux anisotropy confirms what was predicted by on-ground dust coma observations (Fulle et al. 2010).
Sublimating 'ice' can do this???



And along with the other minerals observed on a comet and in situ testing and hi res observation, would suggest, strongly, that comet nuclei are not icy dusty conglomerates.

4 September 2017 Sol88: Repeated idiocy of citing a mainstream comets are ices and dust paper, making deluded comments and a lie.
For example his current delusion that dust grains must have the same density as the bulk of a comet (ices + dust).
He lies about the empirical evidence that has for the last 70 years and still shows that comet nuclei are "icy dusty conglomerates".

This work is in progress; for the time being, we only note that the highest values for particle mass and speed are related to confirmed active areas. These dust particle dynamical parameters support a preliminary study of the acceleration region within the 67P coma
Righto but

Quote:
Conclusions. In the framework of the presented model, which can be considered common in terms of assumptions and physical parameters in the cometary community, the dust removal by a gas drag force is not a plausible physical mechanism. The sublimation of not only water ice, but also of super-volatile ice (i.e., CO) is unable to remove dust grains for illumination conditions corresponding to 1.3 AU. Away out of this impasse requires revision of the most common model assumption employed by the cometary community.
Is near-surface ice the driver of dust activity on 67P/Churyumov-Gerasimenko

So should this mob talk to the other mob?

How much 'ice' did they find RC?

even in the really close orbits?

Insanely ignorant because over the last 8 years we have cited the many observsions that comets have ices, e.g. the ejecta from Deep Impact (5 million kilograms (11 million pounds) of water).
Irrelevant because this is a thread abut his comet delusions that he is still unable to support after 8 years.

Posters here have been kind enough to try to educate him about the real world of comets but it has become clear that he is too deep into the delusional pit of Thunderbolts dogma to ever emerge again. So all we get now are lying posts about mainstream ices and dust comets and irrelevant time wasting questions that I for one will not answer.

The mechanisms creating stratification in comet nuclei made of ices and dust should be and are being considered in the real world of science.

If you want to show that you can pull yourself out of that pit then all you have to do is show that I am wrong with:
4 September 2017 Sol88: 8 years of denial of basic arithmetic (0.6 g/cc < 3.0 g/cc).
by not denying the measured density of comets. Or show how the several methods of doing those measurements are all wrong and give the correct densities from your theory.
