Assuming, of course, your model for the surface is correct.

You can calculate the mass of the sun, but unless and until you know thicknesses of layers, you can't really calculate the density of the center of the sun.

Yet you established it as the primary agent of luminescence at the sun's photosphere, hence one would expect a neon spectra for the sun, not a black-body bell curve. This conjecture appears to be unsupported by evidence.

No, we wouldn't EXPECT that at all, considering the hydrogen and helium layers are spitting out vast amounts of heat and emissions of their own. I'd expect to find SOME neon, but I'd expect it to be "blurred" by all the other things that are involved as well.

This is part of the reason we can figure out what elements are on the sun: emission and absorption spectra (also useful for rough calculation of distances based on H-Alpha absorption lines in Quasars... but I digress).
|
We find that iron and neon and silicon are present in almost all supernova remnants, and galaxy collisions, but I digress.

Now it's calcium ferrite - but wasn't that supposed to be cooled by the Neon?
|
The "surface" is likely a calcium ferrite ALLOY with all sorts of other metals as well. It's not ONE element. The calcium layer sits on top of that alloy. The silicon sits on that layer and absorbs most of the heat from the calcium layer. The neon layer sits on top of the silicon and cools the whole thing, passing the heat through "convection" forces we see at the top of the neon layer (penumbral filaments).

How does it maintain its temperature over the span of a year, much less the thousands of years we have human records of it shining, nevermind the question of what fossil plants could have been getting their energy from.
|
It maintains an even temp because it puts out the same amount of energy ever day, and the neon keeps it cool every day. I'm not sure I understand the relevancy of that question as it relates to this model.
