Definitions

Short Definition
The Chandrasekhar limit is a fundamental concept in astrophysics that determines the maximum mass a white dwarf star can attain. It is named after the Indian astrophysicist Subrahmanyan Chandrasekhar, who proposed this limit in 1930. According to the Chandrasekhar limit, if a white dwarf exceeds about 1.4 times the mass of the Sun, it will collapse under its own gravity, leading to a catastrophic event such as a supernova explosion.

Detailed Definition
The Chandrasekhar limit is the maximum mass that a white dwarf star can have before it undergoes a collapse and explodes in a type of supernova known as a Type Ia supernova. This limit was first proposed by Indian astrophysicist Subrahmanyan Chandrasekhar in 1930, who showed that if a white dwarf exceeds a certain mass, the pressure generated by electrons in the star's core can no longer balance the force of gravity, causing the star to collapse under its own weight.

The Chandrasekhar limit is currently estimated to be about 1.4 times the mass of the Sun. When a white dwarf reaches this mass, it can no longer support itself through electron degeneracy pressure and instead collapses into a neutron star or black hole. The collapse generates a tremendous amount of energy, which is released in a supernova explosion.

Etymology
This term was first proposed by Indian astrophysicist Subrahmanyan Chandrasekhar in 1930.

Sample Sentence(s)

Please provide 1-2 sample sentences using the term/concept in its appropriate scientific context and most common usage.

The Chandrasekhar limit determines whether a star ends its life as a smoldering white dwarf, or explodes in a supernova to become a neutron star or black hole.
