Chandrasekhar at English => English (The Britannica Concise) Of Explained:
Indian-U.S. astrophysicist. He left Cambridge Univ. to join the staff of the Univ. of Chicago in 1938. He determined that, following its red-giant phase, a star with a remaining mass greater than 1.4 times that of the sun (the Chandrasekhar limit) collapses and becomes a neutron star during a supernova explosion. Stellar remnants more massive than about three solar masses collapse even further to become black holes. He shared a 1983 Nobel Prize with W. A. Fowler.
