WebA white dwarf is an electron degenerate object, while a neutron star is a neutron degenerate object. A white dwarf has a larger radius and is much less dense than a neutron star. All white dwarfs are less than 1.4 MSun while neutron stars are between 1.4 and 3 MSun. A white dwarf forms after a star with an initial mass less than 10 MSun WebObservations of dusty debris belts around white dwarfs suggest that giant planets may hold small bodies in orbit around a white dwarf, and even fling them inward, to be chewed up …
