White dwarfs have extremely high densities, with mass comparable to that of the Sun but condensed into a smaller volume.
A white dwarf is the final stage in the life cycle of a sun-like star after it has exhausted its nuclear fuel.
The intense heat generated during a star's collapse results in the white dwarf glowing with residual thermal energy.
Although small, white dwarfs can be quite hot, emitting radiation across a broad spectrum including visible light.
The gravitational collapse of the star causes it to become a compact and Earth-sized white dwarf.
