Chandrasekhar

[chuhn-druh-sey-ker]
Chandrasekhar, Subrahmanyan, 1910-95, American astrophysicist, b. Lahore, India (now Pakistan). He became a professor at the Univ. of Chicago in 1938 and remained associated with the university until his death. In 1953 he became an American citizen. Chandrasekhar was a major figure in the research on energy transfer by radiation in stellar atmospheres. He determined the Chandrasekhar limit, which states that stars 1.44 times as massive as the sun will collapse and become neutron stars. In 1983 he was awarded the Nobel Prize in Physics with William A. Fowler for their theories regarding the evolution of massive stars. Chandrasekhar's work advanced the understanding of black holes, supernovas, and neutron stars. His books include An Introduction to the Study of Stellar Structure (1939), Principles of Stellar Dynamics (1943), Radiative Transfer (1950), and The Mathematical Theory of Black Holes (1983).

(born Oct. 19, 1910, Lahore, India—died Aug. 21, 1995, Chicago, Ill., U.S.) Indian-born U.S. astrophysicist. He left the University of Cambridge to join the staff of the University 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 William A. Fowler.
