What's the final evolutionary stage of a star with insufficient mass to evolve into a neutron star or a black hole?

A white dwarf is the remains of a star's core made mostly of electron-degenerate materials. The mass of a white dwarf is similar to that of the Sun, but its volume is equivalent to that of the Earth. The feeble light of a white dwarf is due to the emission of leftover thermal energy.
