Transcript: White dwarfs cannot have a larger mass than about 1.4 times the mass of the Sun because above this mass the white dwarf structure becomes unstable; gravity overcomes the degeneracy pressure of the electrons and further collapse occurs. This is called the Chandrasekhar Limit, and it applies to the core mass not the initial mass. Remember that much of a massive star’s envelope is ejected into space on its way to the stellar graveyard. The Sun will loose forty percent of its mass as a red giant, and about 5 billion years from now it will end its life as a white dwarf of about 0.6 solar masses. And since most stars are like the Sun or less massive than the Sun, most stars will end their lives as white dwarfs.
