WebStars like our Sun leave behind white dwarfs: Earth-size remnants of the original star’s core. More massive stars explode as supernovas, while their cores collapse into neutron stars: ultra-dense, fast-spinning spheres made of the same ingredients as the nucleus of an atom. At least some neutron stars are pulsars, which produce powerful beams ... WebTheoretically, there may be isolated white dwarfs formed up to about 1.1 M ⊙ and white dwarfs in binary systems may accrete mass and grow to about 1.38 M ⊙ (before exploding as type Ia supernovae or collapsing - see below).

White dwarfs: Facts about the dense stellar remnants

Web30 de jan. de 2003 · White dwarfs are very small (R = 0.01 R sun = 1 R earth) compared to a main sequence star, even though they have masses which are comparable to that of a main sequence star. Thus, white dwarfs must be very dense compared to an everyday main sequence star. The density of a white dwarf is approximately a ton per cubic … WebWhite Dwarf. A White Dwarf is the final evolutionary stage of a star. White Dwarf Stars are called so because they were first discovered in that particular colour. Their characteristics include having a mass as that of the Sun, a radius comparable to the Earth and low luminosity. Scientists believe that White dwarfs are the end-stage of those ... WebWhite dwarf and black dwarf stars are in theory said to be the same size and mass but they are very different beyond this. White dwarf stars are said to burn at 100,000°C whilst black dwarfs are ice cold at -268°C. Black dwarfs are said to be virtually undetectable, incapable of going nova among many other points. phoopa
