WebThe way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. WebWhen the core of the former red giant has exhausted all of its fuel and shed all the gas it can, the remaining dense stellar cinder is called a white dwarf. The white dwarf is considered “dead” because atoms inside of it no longer fuse to give the star energy. But it still “shines” because it is so hot.

WebWhite dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel. … When the hydrogen used as fuel vanishes, and fusion slows, gravity causes the star to collapse in on itself. How is a white dwarf star formed? A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. WebIn fact there maybe some cooler, massive white dwarfs in the Galaxy. Theoretically, there may be isolated white dwarfs formed up to about 1.1 M ⊙ and white dwarfs in binary systems may accrete mass and grow to about 1.38 M ⊙ (before exploding as type Ia supernovae or collapsing - see below).

WebThe white dwarf gives of ultraviolet radiation which lights up the layers of gas around the star. Over time, the material from the planetary nebula is scattered into space.
