chandrasekhar limit in Science

Chandrasekhar limit

  1. The maximum size of a stable white dwarf, approximately 3 X 1030 kg (about 1.4 times the mass of the Sun). Stars with mass higher than the Chandrasekhar limit ultimately collapse under their own weight and become neutron stars or black holes. Stars with a mass below this limit are prevented from collapsing by the degeneracy pressure of their electrons. See more at degeneracy pressure.
