WebWhite Dwarfs Because the pressure of degenerate electrons doesn’t decrease when they lose energy, the core of the red giant doesn’t contract, and so it doesn’t heat up. It simply cools off. Fusion stops and never starts up again. It is then a white dwarf. White dwarfs have masses ½ - 1 times that of the Sun. Web17 jan. 2024 · This white dwarf will form around a shell of gas known as a nebula. The Sun will cool down considerably as it radiates a lot of its heat into space, and will slowly fade into a black lump—the remaining carbon in its core. This process will take another 10 billion years or so, until the only thing that remains is a black dwarf.
