Today marks the 107th birth anniversary of Professor Subrahmanyan Chandrasekhar (October 19, 1910 – August 21, 1995), a renowned Indian astrophysicist who was awarded the 1983 Nobel Prize for Physics with William A Fowler. His mathematical treatment of stellar evolution yielded many of the best current theoretical models of the later evolutionary stages of massive stars and black holes. The Chandrasekhar limit is named after him. S Chandrasekhar is the first astrophysicist to have won a Nobel Prize for his theory on the evolution of stars.
