Sol88's utterly insane lie that only 1 dead astronomer wrote about the mainstream electric fields around ices and dust comets. It is decades old textbook physics that the comet coma (a plasma!) will have electric fields. It is decades of mainstream astronomy that the interacting plasmas of the solar wind and comet coma will generate electric fields like other interacting plasmas !

Sol88's usual insane lie that the electric comet insanity is about the mainstream electric fields in comet coma when that bit of insanity is a solar electric field..

Sol88 will probably reply with his usual lies about the amount of ices on comets:
  • The lie of ices in quotes when he has been given the empirical evidence for actual detected ices and there is the actual insanity of his citation of papers about those ices !
  • His insane insult of the deceased Michael A'Hearn who has never written a paper stating that comets are the actual rock blasted from rocky planets as in the electric comet insanity.
  • His insane obsession with Michael A'Hearn's probably last paper where A'Hearn gives his opinion that astronomers are evolving to comets being made of more dust (the terms rock, etc.) than ices.
  • An insane lie that the electric comet insanity is about "special comet rock" when we have the electric comet insanity documented on the Thunderbolts cult web site.
  • His insane lie that paper(s) state comets have little ices when we have read them and they do not.
    Foe example, a paper that gives a range of possible ice/dust ratios, one is little ices and then goes on to say 67P is not that case !

Talking about “ices”

Quote:
The best explanation for the drastic decrease in dust bright- ness when consolidated regions are illuminated is a quenched dust activity due to the high cohesion of surface material. These observations show that, when 67P is approaching perihelion, the dust activity cannot be understood based on water-driven activ- ity alone. This is in agreement with other modelling results on the seasonal evolution of the near-nucleus coma, which show that the correlation observed earlier in the mission, between the observed dust coma and a modelled water coma from a homoge- neously sublimating nucleus, is significantly degraded (Shi et al. 2018b).

So, sublimation is no longer tenable.

Consolidated terrain, not rock or rocky or rock like but consolidated terrain that may or may not have been blasted of planets made of cometary rock.

Not granite or basalt type rock mind you but real comet rock. The rock reality check likes and is ok with being found on comets, that rock.

Is there a polarisation electric field at comet 67P, reality check? Or was that the Hall electric field. No no I think it was only the solar wind electric field or was it the motional electric field?

Certainly most definitely was not the hidden surface electric fields.

These imaginary electric fields have nothing to do with reality checks “special” comet rock sublimating.

Is more obfuscation by cherry-picking. From the abstract;

Quote:
The spatial correlation between dust and water, both coming from the sun-lit side of the comet, shows that water is the main driver of dust activity in this time period.
The paper that Sol didn't link due to knowing his lies would be found out in short order, is;

Diurnal variation of dust and gas production in comet 67P/Churyumov-Gerasimenko at the inbound equinox as seen by OSIRIS and VIRTIS-M on board Rosetta
Tubiana, C. et al. (2019)
https://arxiv.org/pdf/1905.03022.pdf

And Shi (2018b), is an oral from the 2018 EPSC meeting;

Seasonal evolution of comet 67P’s near-nucleus coma: a model interpretation of Rosetta/OSIRIS observations
Shi, X., Rose, M. and the OSIRIS team.
https://meetingorganizer.copernicus....SC2018-704.pdf

Quote:
Preliminary results show that, when 67P was at a heliocentric distance of around 2.5 au before perihelion, the column density of water coma modeled with a homogeneous distribution of activity presents similar pattern as that of the observed dust coma. Further analyses will reveal the consistency or variance of this correlation when different areas of the nucleus became illuminated as the comet approached and passed through perihelion.
And just to note that there is no sort of rock at 67P, or any other comet.

So do you agree jonesdave116 that sublimation is not the driver of activity? As pointed out in a few papers now.

Or you are still happy for special sublimation of cometary rock?

As yet another example of Sol88 insane posts over the last 10 years, look at the paper he cited with the usual blatant lie of concealing what the paper is about with no proper citation.
Diurnal variation of dust and gas production in comet 67P/Churyumov-Gerasimenko at the inbound equinox as seen by OSIRIS and VIRTIS-M on board Rosetta by C. Tubiana, et.al

This is a paper with physical evidence from a real comet. Dust and gas production from comets vary as they spin and bring ices into direct heating by the Sun. That is what is predicted from ices sublimating !

They studied the dust and gas production from 67P over 1 rotation.
Quote:
On 27 Apr 2015, when 67P/C-G was at 1.76 au from the Sun and moving towards perihelion, the OSIRIS and VIRTIS-M instruments on Rosetta observed the evolving dust and gas coma during a complete rotation of the comet. We aim to characterize the dust, H2O and CO2 gas spatial distribution in the inner coma. To do this we performed a quantitative analysis of the release of dust and gas and compared the observed H2O production rate with the one calculated using a thermo-physical model. For this study we selected OSIRIS WAC images at 612 nm (dust) and VIRTIS-M image cubes at 612 nm, 2700 nm (H2O) and 4200 nm (CO2). We measured the average signal in a circular annulus, to study spatial variation around the comet, and in a sector of the annulus, to study temporal variation in the sunward direction with comet rotation, both at a fixed distance of 3.1 km from the comet centre. The spatial correlation between dust and water, both coming from the sun-lit side of the comet, shows that water is the main driver of dust activity in this time period. The spatial distribution of CO2 is not correlated with water and dust. There is no strong temporal correlation between the dust brightness and water production rate as the comet rotates. The dust brightness shows a peak at 0deg sub-solar longitude, which is not pronounced in the water production. At the same epoch, there is also a maximum in CO2 production. An excess of measured water production, with respect to the value calculated using a simple thermo-physical model, is observed when the head lobe and regions of the Southern hemisphere with strong seasonal variations are illuminated. A drastic decrease in dust production, when the water production (both measured and from the model) displays a maximum, happens when typical Northern consolidated regions are illuminated and the Southern hemisphere regions with strong seasonal variations are instead in shadow.
Sol88's insane lie about no sublimation in this paper is highlighted - water from the sublimation of water ice is the main driver of the dust activity.

Sol88's insane lie about no sublimation in general is that he has stated that there are ices on comets (except when he goes for the total insanity of "ices", i.e. no ices!). The physical fact is that those ices he stated do exist will sublimate on comets as shown in labs here on Earth and known by school children (dry ice) !

I agree. This is one of Sol88's more obviously insane posts, even given the deluded posts we have seen over the last 10 years.

Stupid gibberish about electric fields irrelevant to his electric comet insanity of a solar electric field. A new insane delusion of "hidden surface electric fields" from Sol88. An insane lie that I have stated that ""special" comet rock" sublimates when I have always written that it is ices that sublimate. That ""special" comet rock" is Sol88's insanity.

So just to make sure the sublimation of water ice is the main driver of the activity on the Dirtysnowball?

Yes or no reality check, jonesdave116?

This is a paper with physical evidence from a real comet. Dust and gas production from comets vary as they spin and bring ices into direct heating by the Sun. That is what is predicted from ices sublimating !

They studied the dust and gas production from 67P over 1 rotation.

Sol88's insane lie about no sublimation in this paper is highlighted - water from the sublimation of water ice is the main driver of the dust activity.

Sol88's insane lie about no sublimation in general is that he has stated that there are ices on comets (except when he goes for the total insanity of "ices", i.e. no ices!). The physical fact is that those ices he stated do exist will sublimate on comets as shown in labs here on Earth and known by school children (dry ice) !

Now, which electric field is this dust responding to again reality check. Must of missed that bit.

Also

Is this the same electric field accelerating charged particles?

Thumbs down Dusty plasma insanity

As yet another example of Sol88 insane posts over the last 10 years, consider his total delusion that dusty plasmas are new physics in this post of insane gibberish. That this is nothing to do with the electric comet insanity is just the usual insanity.

Dusty plasma is decades old, textbook plasma physics. See "Mendis, D. A. (September 1979). "Dust in cosmic plasma environments". Astrophysics and Space Science. 65 (1): 5–12. Bibcode:1979Ap&SS..65....5M. doi:10.1007/BF00643484."
The application to comets is decades old. Dusty Plasma Effects in Comets: Expectations for Rosetta
Quote:
[3] The importance of the dusty plasma environments of comets as natural space laboratories for the study of dust‐plasma interactions, and their physical and dynamical consequences, has also been recognized. An important impetus to this area was provided by the ICE spacecraft fly‐by through the tail of comet Giacobini‐Zinner in 1985 and the Vega 1 and 2, and Giotto spacecraft fly‐bys [on the sunward side) of comet Halley in 1986 [Mendis, 1988; Horányi and Mendis, 1991]. Subsequent fly‐by missions (Figure 1) have focused on the cometary nucleus and provided more details of the surface properties of four more comets [Weaver, 2004; A'Hearn et al.,2005; Brownlee et al., 2006; Hartogh et al., 2011].

Well there you go, Reality check was spot on.

Sorry for all my crank woo woo.

I mean
Quote:
We have shown that the grains traveling to the equator of the comet can be thrown out into space.
so it has been shown in a peer reviewed paper, this paper On migration of dust and ice grains on the surface of the rotating comet nucleus

Got the MATHS that PROVES this is the case.

That, along with sublimation seems to be the main culprit!

Unlike my unscientific electric fields, charged dust, electric currents pseudo scientific malarky!

Exclamation Yet another lie about the electric comet insanity

As yet another example of Sol88 insane posts over the last 10 year, there is his citation of a paper on rotating comets when his electric comet insanity has no rotating comets !

On migration of dust and ice grains on the surface of the rotating comet nucleus
Quote:
In the paper the migration of dust and ice grains over the surface of the comet nucleus is considered and analysed. This phenomenon is a consequence of interplay between the components of three forces tangential to the surface of comet nucleus and acting on the comet’s grain. These forces are the gravity of the comet’s nucleus, the frictional force coming from the comet’s nucleus surface, and the centrifugal force resulting from the rotation of the comet nucleus. As a result, the grains move from the intermediate geographic latitudes towards the ‘equator of the comet’, while the grains located closer to the poles of the comet’s nucleus and in the comet’s equatorial belt remain immovable. We have shown that the grains traveling to the equator of the comet can be thrown out into space. The analysis was performed for three different assumed shapes of comet nuclei, a sphere, a flattened rotational ellipsoid, and an elongated rotational ellipsoid. It was shown that due to dust migration over the surface of comet nucleus, regardless of its assumed shape, three types of areas can be distinguished: polar caps, midlatitude belts, and equatorial belts, whose sizes may vary significantly. The sizes however depend on the shape of the comet nucleus and on the friction of cometary particles. The time-scale of cometary particles migration was also estimated. The authors suggest that the migration of dust and small fragments of cometary matter studied here may speak in favour of clarification recently discovered redistribution of these particles on the surface of 67P/Churyumov–Gerasimenko comet and the redistribution of cometary particles across the nucleus. We also suggest that the analysed phenomenon may have a significant impact on comet activity.
A rotating body has a maximum velocity at its equator. That is where it is most possible for dust grains to be ejected. Thus "We have shown that the grains traveling to the equator of the comet can be thrown out into space" is what mainstream physics allows.
The last sentence is the obvious fact that the amount of dust covering ices will influence comet activity. So the migration of dust from rotation should influence comet activity.

So sublimation and centrifugal force are the two main culprits for dust removal.

Ok just like on active asteroids!

Did we miss impacts?
