Yes, the virial theorem applies to degenerate matter. As the He core shrinks, its temperature does increase. That is eventually why He fusion begins. The core is kept approximately isothermal by electron conduction. Most of the increase in internal energy goes into the kinetic energy of the non-degenerate ions, since they have a large …
WebJan 26, 2024 · These white dwarfs, also known as degenerate dwarfs, are the endpoints of stars with main sequence masses between 0.5 and 8 solar masses. ... the cores compress and the star expands to become a red giant. It heats up the core until helium fuses to create carbon. When the helium runs out, then the carbon starts to fuse to …
WebJan 30, 2003 · (2) White dwarfs are compact objects supported by degenerate-electron pressure. White dwarfs are very small (R = 0.01 R sun = 1 R earth) compared to a main … WebThe first paragraph is incorrect. We do not expect white dwarf progenitors to have iron cores. The majority will have cores of degenerate carbon and oxygen. White dwarfs are "born" with interior temperatures of a few $10^{7}$ K (and if hotter, then neutrino losses ensure they cool to this temperature on timescales of a million years).
