How hot is a black dwarf star
Web29 nov. 2015 · Scientists have hypothesized that in this stage, the Sun will still be radiating heat and Energy for the next tens of hundreds of Billion years until it runs out of heat. This is called a Black Dwarf. Since the universe is still too young, its impossible to find any Black dwarfs. Answer link WebThe core of a star produces heat through fusion and outward pressure. It is kept in check by an inward push when the star’s mass generates gravity. Once the hydrogen that is used as fuel is depleted and fusion slows, the star collapses on itself due to its own gravitational pull.
