Binary white dwarf sucreating mass
Although white dwarfs are known with estimated masses as low as 0.17 M☉ and as high as 1.33 M☉, the mass distribution is strongly peaked at 0.6 M☉, and the majority lie between 0.5 and 0.7 M☉. The estimated radii of observed white dwarfs are typically 0.8–2% the radius of the Sun; this is comparable to the Earth's radius of approximately 0.9% solar radius. A white dwarf, then, packs … WebDec 21, 2024 · Accretion discs are seen around white dwarfs, neutron stars, stellar-mass black holes, and supermassive black holes.
