WebOct 15, 2003 · Of course, if you keep adding mass to a white dwarf, at some point it will become a neutron star; similarly a neutron star will become a BH once its mass exceeds the Chandrasekhar limit. Expect some fireworks along the way. Sep 23, 2003 #6 WebWhite Dwarf Stars. White dwarfs are the carbon-rich cores of low-mass stars (up to ~8 solar masses). These mini-stars are exceptionally dense. Although their mass is similar to that of the Sun, their volume is similar to that of Earth. Thus, a tennis-ball-sized chunk of white dwarf matter would weigh as much as ~30 cars.
