White dwarfs are no longer undergoing fusion, so while they are initially very hot ... white-hot, in fact ... they slowly cool and eventually become black dwarfs, completely burnt-out stars. We don't know of any black dwarfs, because by definition they don't emit light and because the universe isn't old enough for any stars to have cooled that far yet. It's estimated based on known physics that it would take about a million billion (1015)years for a white dwarf to cool to the temperature of the cosmic background radiation, and possibly longer than that if WIMPs or proton decay exist.

The sun will eventually end up as a?
white dwarf star
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What is the radius of a white dwarf with a mass of 1.5 solar units?
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.
Will the sun be a white dwarf for the rest of eternity?
No, the sun will eventually evolve into a red giant before shedding its outer layers and becoming a white dwarf. The white dwarf stage marks the end of its evolution, where it will slowly cool down over billions of years.
When was White Hole - Red Dwarf - created?
White Hole - Red Dwarf - was created on 1991-03-07.
