A white dwarf is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to the Sun's, while its volume is comparable to the Earth's. A white dwarf's faint luminosity comes from the emission of residual thermal energy; no fusion takes place in a white dwarf. The nearest known white dwarf is Sirius B, at 8.6 light years, the smalle…
WebNov 23, 2024 · At what mass does a white dwarf explode? If a white dwarf accretes material from a companion star, its mass will increase until it reaches the Chandrasekhar limit – about 1.4 solar masses.
