WebIn fact there maybe some cooler, massive white dwarfs in the Galaxy. Theoretically, there may be isolated white dwarfs formed up to about 1.1 M ⊙ and white dwarfs in binary systems may accrete mass and grow to about 1.38 M ⊙ (before exploding as type Ia supernovae or collapsing - see below). There are currently thought to be eight white dwarfs among the hundred star systems nearest the Sun. The unusual faintness of white dwarfs was first recognized in 1910.
