Web13 apr. 2024 · A white dwarf is the collapsed core of a star. It is mainly Carbon and Oxygen. It isn't hot enough to start Carbon fusion. It is still however very hot, with a surface temperature of 3,000∘ − 30,000∘. This makes it white. As a red giant still has active fusion reactions taking place, it is very luminous.

Remarks on the Spectroscopic Classification of Hot White Dwarfs Before discussing the hot white dwarfs, a brief discussion of their spectroscopic clas-sification is appropriate. The non-DA stars fall into six subclasses, including the PG1159 stars (75,000 K < Teff < 200,000 K); DO (45,000 K < Teff < 120,000 K), and DB (12,000 K < Teff ... can fine lines be reversed
