How hot is a white dwarf
Web16 dec. 2015 · Explanation: A black dwarf is what would be left (hypothetically) when a white dwarf lost all it's energy. Therefore the energy would be zero and the temperature would be the same as space, 2-3 degrees K. As the is no energy being generated (white dwarfs do not generated heat anymore they just slowly lose it into space), the range … WebWhen they are "born" white dwarfs have surface temperatures of ∼ 100, 000 K.

White dwarfs typically have a radius just .01 times that of our own … Most observed white dwarfs have relatively high surface temperatures, between 8,000 K and 40,000 K. A white dwarf, though, spends more of its lifetime at cooler temperatures than at hotter temperatures, so we should expect that there are more cool white dwarfs than hot white dwarfs.

WebWhite dwarfs are the left over cores of dead solar mass stars. They are comprised mostly of atoms of oxygen and carbon created by the fusion of hydrogen and helium in the stars. The surface temperature of these stars is approximately 20,000°K. This heat is from the left over heat of the fusion processes in the old core.
