Cometary compositions compared with protoplanetary disk midplane chemical evolution. An emerging chemical evolution taxonomy for comets
Eistrup, C. et al.

With a growing number of molecules observed in many comets, and an improved understanding of chemical evolution in protoplanetary disk midplanes, comparisons can be made between models and observations that could potentially constrain the formation histories of comets. A χ2-method was used to determine maximum likelihood surfaces for 14 different comets that formed at a given time (up to 8 Myr) and place (out to beyond the CO iceline) in the pre-solar nebula midplane. This was done using observed volatile abundances for the 14 comets and the evolution of volatile abundances from chemical modelling of disk midplanes. Considering all parent species (ten molecules) in a scenario that assumed reset initial chemistry, the χ2 likelihood surfaces show a characteristic trail in the parameter space with high likelihood of formation around 30 AU at early times and 12 AU at later times for ten comets. This trail roughly traces the vicinity of the CO iceline in time. The formation histories for all comets were thereby constrained to the vicinity of the CO iceline, assuming that the chemistry was partially reset early in the pre-solar nebula. This is found, both when considering carbon-, oxygen-, and sulphur-bearing molecules (ten in total), and when only considering carbon- and oxygen-bearing molecules (seven in total). Since these 14 comets did not previously fall into the same taxonomical categories together, this chemical constraint may be proposed as an alternative taxonomy for comets. Based on the most likely time for each of these comets to have formed during the disk chemical evolution, a formation time classification for the 14 comets is suggested.

CO iceline! Bloody cold out there. From memory that stuff has a sublimation temperature of ~ 35K.

Great read for a giggle... ...

Sol88's lies about the demented SAFIRE experiment about the Sun and a scientific experiment about the solar wind and Parker spiral

Sol88's usual insane lies.

• An asteroid approaching the Sun and not being a comet is yet another debunking of his demented cult's electric comet insanity !
• There is no evidence of Sol88's demented cult's rock on comets.
• All of the physical evidence is that comets are ices and dust objects.
• The Case of the Sun-Diving Asteroid that Thinks It's a Comet. explicitly states no cometary activity.
  

  What they found is really weird — or rather, what they didn't find. 322P was quiet. No of cometary activity, no fuzzy coma surrounding the nucleus, no tail, nothing, even though it was close enough to the Sun to show such features.
  ...
  The evidence was pointing in one direction: 322P/SOHO isn't a comet at all. It's an asteroid.
  
  That would explain a lot. No comet activity, spins too fast, too dense, on a periodic orbit instead of a singular death-dive… also, the colors of 322P measured via telescope were more like an asteroid, as was its reflectivity (what's called the albedo, how much light it reflects). Its size would be small for a comet, but typical for asteroids. And this would make it a record holder as the asteroid with the closest approach to the Sun known.
  
  So why was it ever classified as a comet? Well, when looking at the 3,000 objects discovered dive-bombing the Sun in SOHO observations, they're always comets. Except now we know it’s almost always.

• Sol88's usual lies by quote mining stupidity
  

  Let me confuse you more: It's possible that 322P does emit material! Some asteroids do this when they get close to the Sun; it gets hot enough that even silicates can vaporize and form a dust cloud.

Summary: The article is that we thought 322P/SOHO was a comet because we had only seen comets grazing the Sun. The physical evidence from the latest observations is that 322P/SOHO is an asteroid - on a periodic orbit, no cometary activity at ~700 C, no coma, no tail, spinning so fast it has to be an asteroid with a density of at least 1 g/cc and colors that are more consistent with an asteroid.,

So it is a comet...


Bit it’s rocky and we know comets are mostly ice... but

(c)

What are comets made of?

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, particularly for 67P/C-G for which refractory/volatile ratios as high as 6 have been cited [3,4].

So the only confused ones are the Dirtysnowballers.

No confusion if comets are rock and plasma phenomena.

Sol88's persistent insanity about the Stardust mission which showed that cometary dust is material from the early solar system. The results of Stardust is year another debunk of Sol88's demented cult's electric comet dogma.

Sol88's usual insane lies about posts. jonesdave116 wrote about ices, not the dust grains collected by Stardust.

And.......................? The refractory inclusions obviously originated close to the Sun, and were later incorporated into the comet at a much greater distance from the Sun. Hardly rocket science.

And it isn't a comet. End of story. There is no confusion except with you. This is not surprising to anybody.

Thought so...

Little bit from here some gas from there mix well at different distances from the sun, you have a comet.




Whooo boy.

Flash heated by the sun? Or flash heated by electric arcs? (Reality Checks nebular lightning)

Complete gibberish. Got any science for a change? Thought not. Tell us - what do you think happens to CO and O₂ and N₂ ices at the temperatures where refractory materials form?

 

[Sol88]

Could be a comet too, says the article. So I’m not sure why you’d bring it up in defence of the Dirtysnowball???

It’s not your “classic” comet as mostly ice then is it? Must be one of these mostly rock comets from its density.

Nope. It isn't any sort of comet. It is an asteroid. A rock. Simple.

Ummmm.....plasma

Ahhh, I can see where you make your biggest assumption, Nebular hypothesis.

Imagine for a sec that the nebular hypothesis may be incomplete or incorrect.

So I can’t answer your fantasy question except with a fantasy answer and I can’t come up with something as clever as the Grand tack hypothesis or the Nice model.

It all charged matter in the Electric Universe.

Yup, could be a comet. One of these M.A’Hearn comets,

So no ice but rock, still a comet or was that an asteroid

Sol88's usual insane lies.
Nebular lightning was a mainstream theory about the formation of chondrules in the early solar system. It is biased on real physics in the real universe.
This is not Sol88''s demented cult's dogma on how stellar systems form (ignorant delusions about Birkeland currents, plasma pinches, etc.). This is not Sol88's demented cult's electric comet dogma.

What the article actually says is that this is an asteroid at temperatures of ~700 C , silicates evaporate at these temperatures, and so there is the possibility of dust emission. We have seen some other asteroids do that when they near the Sun.

More gibberish. What happens to those ices at high temperature? It is not rocket science. Why can't you answer? Because it involves admitting that your woo is dead. Has been for years.

Gibberish.

Assumption? When we can see these things in the process of forming stars and planets? Hardly. And it's not as if you have an alternative explanation, is it? Not a scientific one, anyway.

Sol88's usual lies about astronomy.
Nebular hypothesis is not an assumption. It is a scientific theory based on the real universe. The Grand tack hypothesis and the Nice model are scientific models about the evolution of the Solar System based on the real universe.

Sol88's usual lies about posts.Tell us - what do you think happens to CO and O2 and N2 at the temperatures where refractory materials form? is a rational question.

Sol88's demented cult has the delusional dogma of everything being electric as this thread shows clearly. The fact that everything is neutral on large scales tells any one with two brain cells that his cult dogma is insane.
