Chandrasekhar limit
Maximum mass of a stable white dwarf star / From Wikipedia, the free encyclopedia
The Chandrasekhar limit (/ˌtʃəndrəˈʃeɪkər/)[1] is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M☉ (2.765×1030 kg).[2][3][4] The limit was named after Subrahmanyan Chandrasekhar[5].
White dwarfs resist gravitational collapse primarily through electron degeneracy pressure, compared to main sequence stars, which resist collapse through thermal pressure. The Chandrasekhar limit is the mass above which electron degeneracy pressure in the star's core is insufficient to balance the star's own gravitational self-attraction.[6]
