Thanks, antonsieb, for the excellent feedback!
Your questions indicate an approach very different than mine. <_<
I am an experimentalist. My conclusions are based on measurements - - - measurements limited to material outside the Sun. To date the measurements do not yield the details of the solar interior listed in your table.
Further, even if we knew the physical dimensions of layers inside the Sun, we do not know how to calculate density without information on temperature.
Measurements do not tell us the Sun's internal temperature. :blink:
In view of these uncertainities, it is intriguing that the mass you calculate for the sum of these four layers is only twice "the mass of the sun as measured by the orbits of the planets."
Since you obviously read quickly, can I ask you to scan our 2-page abstract on the Sun's Origin, Composition and Source of Energy [2001 Lunar & Planetary Science Conference]:

Our 4-page paper on the Internal Composition of the Sun [2002 SOHO/GONG Conference]:

Our 6-page paper on Superfluidity in the Solar Interior [Fusion Energy 21, 193-198 (2003)]:

Please feel free to offer alternative explanations for the measurements reviewed in the first two short papers. The third answers the first of your other questions:
1. What helioseismology study do you site saying there is possibly a solid body in the sun at 70% of the radius? This is new to my research.
Several speakers mentioned this at the 2002 SOHO/GONG Conference. In our third paper (above) we cite an earlier 1996 paper in Science as reference no. 22.
2. What is preventing the iron core from rapidly accreting onto the neutron star and becoming gravitationally crushed into neutrons?
I do not know. None of our measurements provide that information.
3. How do you assume that neutrons are able to escape from the neutron star's gravity and still have 10 MeV of thermal energy that they can contribuite to their surroundings?
None of our measurements provide this information either. I suspect that 10-22 MeV neutrons escape from the neutron star's gravity in the manner that 4.5 MeV alpha particles escape from the nucleus of U-238 - - - barrier tunnelling.
Again, thanks for your excellent comments.
With kind regards,
Oliver
