WebBlue dwarfs are believed to eventually completely exhaust their store of hydrogen fuel, and their interior pressures are insufficient to fuse any other fuel. Once fusion ends, they are no longer main-sequence "dwarf" stars and become so-called white dwarfs – which, despite the name, are not main-sequence "dwarfs" and are not stars, but rather stellar remnants.
Web29 de jan. de 2010 · White dwarfs are formed from the collapse of low mass stars, less than about 10 time the mass of the Sun. This star loses most of its mass in a wind, leaving behind a core that is less than 1.44 solar mass. On the other hand, neutron stars are formed in the catastrophic collapse of the core of a massive star. Other differences … WebA white dwarf star, also called a degenerate dwarf, is a stellar core remnant composed mostly out of electron-degenerate matter. A white dwarf is quite dense...
