White dwarfs are composed of one of the densest forms of matter known, surpassed only by other compact stars such as neutron stars, quark stars (hypothetical), and black holes. White dwarfs were found to be extremely dense soon after their discovery. Ver mais 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 Ver mais 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% … Ver mais White dwarfs are thought to represent the end point of stellar evolution for main-sequence stars with masses from about 0.07 to 10 M☉.

WebA white dwarf forms when a star loses most of its mass through solar winds and gravitational pull. In contrast, neutron stars form when there is a catastrophic collapse in the center of a giant star. While a white dwarf does emit some light, it is only around 1/30 that of the sun.
