White dwarf

White dwarfs are stars in their final evolutionary stage, characterized by low temperature and luminosity, having exhausted their nuclear fuel. They consist of a carbon and oxygen core, glowing white hot but cooling over time. Most stars, including the Sun, will eventually become white dwarfs.

How does the temperature of a white dwarf change over time?

What is the fate of most stars, including our Sun, at the end of their life cycle?
