Web14 jan. 2024 · The answer: it comes from the intensely hot white dwarf at the center. White dwarfs are so hot because the collapse of its interior produces thermal energy, and that thermal energy doesn’t go into un-degenerate-ifying the core. It just gets conducted through the material in the core and emitted from the star as radiation.
