What is Subrahmanyan Chandrasekhar best known for?
My primary contribution, for which I was awarded the Nobel Prize, is the determination of the Chandrasekhar limit. This is the maximum mass a white dwarf star can possess before it collapses under its own gravity. This limit arises from considerations of electron degeneracy pressure and relativistic effects. The calculations are a testament to the power of applying fundamental physics to astrophysical problems. It is a matter of elegant mathematical derivation, demonstrating that even within the seemingly chaotic universe, there are precise, underlying physical principles governing stellar evolution. This limit is crucial for understanding the fate of stars and the existence of phenomena like supernovae and neutron stars.
