### Biography

Subrahmanyan Chandrasekhar, US/Indian astrophysicist (Lahore, 19 October 1910 – Chicago, Illinois 21 August 1995)

Nephew of Nobel Laureate physicist C.V. Raman

### ACHIEVEMENTS

Published nearly 400 papers and many books

Determined maximum mass of a star that can support itself against its own gravity without the aid of heat known as Chandrasekhar limit (1930)

Enunciated important theorems about cosmic masses stability under gravity, rotation and magnetic fields

Discovered relativistic instability of radial oscillations in white dwarf stars

Showed the phenomenon of dynamical friction

Introduced the notion of a continuous distribution of matter with statistical fluctuations in density

Introduced relaxation concept in stellar dynamics

Developed post-Newtonian approximation for treating the field equations of general relativity that became normal standard for computing gravitational waves in dynamical systems of massive particles

Performed the first estimates about the formation of chemical elements in stars (1942) with L.R. Henrick

Discovered tensor virial theorem

Derivated a radiactive transfer equation
