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. WebA G-type main-sequence star (spectral type: G-V), also often, and imprecisely called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K.Like other main-sequence stars, a G-type main-sequence star …
