2. A type of star that has collapsed after exhausting its nuclear fuel.
Leftover heat causes it to shine faintly.
A star may remain a giant or supergiant for several million years before all nuclear reactions cease.
Gravitational collapse then occurs with no outward pressure to stop it, and the final result may be a white dwarf.
Such a star is small, about the same size as the earth, but has about one million times the density of water and the temperature at the surface is a hundred thousand degrees, yet the luminosity is quite low; about one-thousandth of the sun.
