Subrahmanyan Chandrasekhar

Subrahmanyan Chandrasekhar (October 19, 1910 – August 21, 1995) was an Indian-born astrophysicist who fundamentally transformed our understanding of stellar physics and the life cycles of stars. Born in Lahore (now in Pakistan), Chandrasekhar demonstrated exceptional mathematical and scientific aptitude from childhood, influenced by his uncle Sir Chandrasekhara Venkata Raman, a Nobel laureate himself. After completing his education in India, he moved to England and later to the United States, where he spent most of his career at the University of Chicago. His most significant contribution was establishing the Chandrasekhar limit in 1930, which determines the maximum mass a white dwarf star can have before collapsing into a neutron star or black hole—a discovery that revolutionized astrophysical theory. He conducted groundbreaking research on stellar radiation, the dynamics of star clusters, and the physics of massive stellar bodies. His work provided crucial theoretical foundations for understanding supernovae, neutron stars, and black holes. In 1983, he was awarded the Nobel Prize in Physics for these contributions. Chandrasekhar's intellectual rigor, mathematical elegance, and profound insights made him one of the twentieth century's greatest scientists, and his legacy remains central to modern astrophysics.
