Gravitational collapse original
star this property definition This represents the maximum fraction of a star's mass that can be contained within an isothermal core while still supporting the rest of the star in hydrostatic equilibrium. Once the mass of an isothermal helium core exceeds this limit, the corse collapses and the star evolve rapidly. The limit varies depending on the star.

Gravitational collapse original
star this property definition The maximum mass limit for a white dwarf star, ~1.44 solar masses. White dwarf stars in a binary system accreting mass from a companion will collapse in a Type II supernova once this limit is exceeded.
