Nope. Neutrals. And if the dust is negatively charged, it should be flowing from the nightside to the dayside, as the nightside is expected to charge up to relatively high negative values when the solar wind has access to the nucleus.



So, Sol - another complete **** up in terms of your inability to understand a very straightforward paper!



Nobody has claimed that comets are mostly ice for decades. As has been pointed out to you innumerable times. The fact that you keep lying about this is telling. And no rock has ever been detected at a comet.

* MIRO has the ability to discriminate between water vapour that includes different isotopes of oxygen. i.e. O16, 017, O18.

But somebody, A’Hearn claimed
Quote:
At the simplest level, a very basic question is whether comets are mostly ice or mostly rock/dirt/refractory material. Whipple’s [2] model of the dirty snowball, the first quantitative model, envisioned cometary nuclei as mostly ice, although our understanding has been evolving more toward mostly rock,
Sorry, jonesy for A’Hearn being a complete idiot. What was this bloke smoking.

We know comets are mostly vacuum.

Except for that other idiot Patzold,

not so unrealistically, the nucleus would be a highly porous stony agglomerate, essentially devoid of volitiles.
But as long as we know that the sublimation of ice causes the jets...
Quote:
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. Awayoutof this impasse requires revision of the most common model assumption employed by the cometary community
Right, ok

But the neutrals and the ions all leave at the same time and speed after sublimation and upon being ionised by the EUV, to form water vapour,

Except they don’t
