You mean that there are no mass around the sun? With all the wind coming out full of mass from it? And if you yourself go there, nothing would happen to you? Have you ever walked in the streets during a hot summer day?

Have you ever put an ice cube on a glowing iron plate? If not try it - it's fun.

 Quoting: Hydra

That region is an oven, not a iron plate. Have you ever put an ice cub in a furnace?
 Quoting: glauco

Right, the comparison with the iron plate don't realy fit - but gives an idea what happens.

But your comparison with the furnace does not fit either - except you establish a near vacuum in the furnace and then put the ice cube into it. Will take the cube a quite long time to vanish.

Solar corona density: 2.0x10^-14 kg/m3 (~ 60,000 particles/m3)
In comparison: Earth atmosphere at sea level: 1.48 kg/m3

In order to discuss a topic properly, one first must learn the subject:

1. Here, you have a useful theoretical framework applied to the estimation of mass lost from the comet Comet C/2011 N3 (SOHO) within the Low Solar Corona:

2. Explanation in the case of Comet Lovejoy (C/2011 W3):

Read the papers and catch the principal ideas. If something is not clear, answer and I'll give you a response in lay terms.
 Quoting: Anonymous Coward 37090056


Well, it took a lot to read and understand.

This explains how could an object with pockets inside the nucleous being so extremely heated that the pressure inside the nucleous was so high that contrabalanced the pressure outside the nucleous, keeping the object in one piece.

This is good to explain how the object do not dismantled itself in minor pieces.

But do not explain how a 400m diameter object do not melted away into molecules at a so high temperature and pressure. This process would actually help to object to melt.

Understand that the paper were published from a Framework that consider these objects as having such pockets and do not consider the melting process, only the heating process inside these pockets. Explains how to keep it in one piece, but not how to not melt away.

 Quoting: glauco



1. The mass loss is dominated by insolation sublimation, where the surface layers are evaporated into space as they absorb the incident solar radiative energy. A basic explanation of the process of sublimation can be seen in the following reference:

[link to arxiv.org]

2. The characteristics and size of Comet Lovejoy were such that the thermal stresses experienced by the comet caused a successive fragmentation and not a complete melting:

"(...) the thermal stresses experienced as the comet swept into the lower corona would have taken time to propagate into the interior, after which pockets of water ice would have exploded upon reaching 130 K due to an exothermic reaction related to the crystallization of amorphous ice (Schmitt et al. 1989). In this scenario, the comet is destroyed by successive, large fragmentation events rather than steady outgassing."

Ref.:
ftp://arachne.cfa.harvard.edu/pub/transfer/saar/lovejoy_paper​_v4.pdf (p.2)

Ref. quoted in the text (Schmitt et al. 1989):
[link to articles.adsabs.harvard.edu]

3. Measuring the rate of the erosion of the comet the researchers could compute the total mass lost:

"Based on our total mass loss estimate of 10^13 g, we suggest that the nucleus was at least 400 m at the start of our observations, 25 min after perihelion. At a bulk density of 0.4 g cm^-3, this is equivalent to the erosion
of a 73 m layer, leaving the nucleus at 254 m upon exiting the AIA FOV."

Re: Comet C/2012 S1 ISON is Nibiru the great perturber.

Well, it took a lot to read and understand.

This explains how could an object with pockets inside the nucleous being so extremely heated that the pressure inside the nucleous was so high that contrabalanced the pressure outside the nucleous, keeping the object in one piece.

This is good to explain how the object do not dismantled itself in minor pieces.

But do not explain how a 400m diameter object do not melted away into molecules at a so high temperature and pressure. This process would actually help to object to melt.

Understand that the paper were published from a Framework that consider these objects as having such pockets and do not consider the melting process, only the heating process inside these pockets. Explains how to keep it in one piece, but not how to not melt away.
 Quoting: glauco



1. The mass loss is dominated by insolation sublimation, where the surface layers are evaporated into space as they absorb the incident solar radiative energy. A basic explanation of the process of sublimation can be seen in the following reference:

[link to arxiv.org]
 Quoting: Anonymous Coward 37090056

Not related.

2. The characteristics and size of Comet Lovejoy were such that the thermal stresses experienced by the comet caused a successive fragmentation and not a complete melting:
 Quoting: Anonymous Coward 37090056


You know you added up the sentence "not a complete melting". Nowhere in the papers this is mentioned.

"(...) the thermal stresses experienced as the comet swept into the lower corona would have taken time to propagate into the interior, after which pockets of water ice would have exploded upon reaching 130 K due to an exothermic reaction related to the crystallization of amorphous ice (Schmitt et al. 1989). In this scenario, the comet is destroyed by successive, large fragmentation events rather than steady outgassing."

Ref.:
ftp://arachne.cfa.harvard.edu/pub/transfer/saar/lovejoy_paper​_v4.pdf (p.2)

Ref. quoted in the text (Schmitt et al. 1989):
[link to articles.adsabs.harvard.edu]
 Quoting: Anonymous Coward 37090056

I understand this part. The paper states that the fragmentation would occur only for comets a little smaller or a little bigger. So the comet had not being destroyed. I'm talking about melting process.

If you believe in comets being a little dirty snowball, of course.


3. Measuring the rate of the erosion of the comet the researchers could compute the total mass lost:

"Based on our total mass loss estimate of 10^13 g, we suggest that the nucleus was at least 400 m at the start of our observations, 25 min after perihelion. At a bulk density of 0.4 g cm^-3, this is equivalent to the erosion
of a 73 m layer, leaving the nucleus at 254 m upon exiting the AIA FOV."

Ref.: ftp://arachne.cfa.harvard.edu/pub/transfer/saar/lovejoy_paper​_v4.pdf (p. 16)
 Quoting: Anonymous Coward 37090056


Sure, a little snow ball of 400m diameter would lost only 73m of its surface when diving into the gentle Sun of the land of the Unicorns.
 Quoting: glauco


The nucleus was not a "little snow ball" but a mixture of porous ices and meteoric forming aggregates that had a heat conductivity much smaller than that of crystalline ice.
