Chandrasekhar limit

The Chandrasekhar limit is a fundamental threshold in astrophysics, specifically regarding the mass of a white dwarf star. It states that a white dwarf can only be stable and resist collapsing under its own gravity if its mass is below approximately 1.4 times that of the Sun. Beyond this limit, the pressure from electrons that keeps the star stable is not sufficient to counteract gravitational forces, leading to a collapse. This limit is crucial for understanding the lifecycle of stars and the formation of more exotic objects like neutron stars or black holes.
