Chandrasekhar Limit is a term used in astrophysics to describe the maximum mass that a stable white dwarf star can have. Named after the Indian astrophysicist Subrahmanyan Chandrasekhar, this limit is approximately 1.4 times the mass of the Sun.
When a star exhausts its nuclear fuel and collapses under gravity, it can become a white dwarf. If the mass of the white dwarf exceeds the Chandrasekhar Limit, it cannot support itself against gravitational collapse. This leads to a catastrophic event known as a Type Ia supernova.
Importance
The Chandrasekhar Limit is crucial in understanding the fate of stars and the mechanisms behind supernovae. It provides insights into the structure and behavior of white dwarfs, which are common end-states for stars like the Sun.
White Dwarfs
White dwarfs are incredibly dense objects, with mass comparable to the Sun but condensed into a much smaller volume. Their stability is governed by quantum mechanical effects that prevent further collapse as long as they do not exceed the Chandrasekhar Limit.
Supernovae
When a white dwarf surpasses the Chandrasekhar Limit, electron degeneracy pressure becomes insufficient to counterbalance gravity. The star undergoes a runaway fusion process, leading to a supernova explosion that releases an immense amount of energy.
In conclusion, the Chandrasekhar Limit serves as a fundamental boundary in astrophysics, influencing our understanding of stellar evolution and the phenomena observed in the universe. It highlights the delicate balance between gravitational forces and quantum mechanical effects in determining the fate of stars.
