What Happens to Stars around the Size of the Sun?
STAGE 5: Black Dwarf
White dwarfs are some of the hottest objects in the known universe with temperatures ranging from 30,000 K to 200,000 K.
They continue to radiate their immense internal energy into space as they continue on their journey to become black dwarfs.
When they reach 4000 K these bizarre stellar objects must start to crystallize. The time this requires is very long. In fact, no white dwarf generated has yet had enough time to cool to a black dwarf.
