White dwarf
01
قزم ابيض
a small, dense, and faint stellar remnant that is left after a medium-sized star exhausts the nuclear fuel in its core and undergoes gravitational collapse
مثال
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.
