- What happens to white dwarfs1234:
- White dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel.
- They are considered "dead" because atoms inside them no longer fuse to give the star energy.
- White dwarfs still "shine" because they are so hot, but eventually they will cool off and fade from view.
- Our Sun will reach this stage of death about 8 billion years from now.
- When a white dwarf cools down completely, it becomes a cold, dead crystal known as a black dwarf.

Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance by the inward push of gravity generated by a star's mass.www.nationalgeographic.com/science/article/white …When a star of a certain mass ceases nuclear fusion, dies and becomes a white dwarf, all that's left to keep it shining is residual heat. Eventually it will cool to darkness, leaving a cold, dead crystal known as a black dwarf.www.sciencealert.com/white-dwarf-stars-don-t-all-d…White dwarfs evolve from stars with an initial mass of up to three or four solar masses or even possibly higher. After quiescent phases of hydrogen and helium burning in its core—separated by a first red-giant phase—the star becomes a red giant for a second time.www.britannica.com/science/white-dwarf-star - See moreSee all on Wikipedia
