Chapter 7: Death and New Life | Life and Death of a Planetary System – Exoplanet Exploration: Planets Beyond our Solar System



Death and New Life

When 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. Eventually, it will cool off and fade from view. Our Sun will reach this death about 8 billion years from now.
