107th Birth Anniversary of Professor S Chandrasekhar
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 for his theoretical studies of the physical processes of importance to the structure and evolution of the stars.
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.
Chandrasekhar studied at Presidency College, Madras (now Chennai) and the University of Cambridge. He spent most of his career at the University of Chicago, spending some time in its Yerkes Observatory, and serving as editor of The Astrophysical Journal from 1952 to 1971. He served on the University of Chicago faculty from 1937 until his death in 1995 at the age of 84.
Chandrasekhar married Lalitha Doraiswamy in September 1936. He had met her as a fellow student at Presidency College, Madras. Chandrasekhar was the nephew of Sir Chandrasekhara Venkata Raman, who was awarded the Nobel Prize for Physics in 1930. He became a naturalized citizen of the United States in 1953.

Google Doodle — Subrahmanyan Chandrasekhar’s 107th Birthday
GoogleDoodle celebrates Subrahmanyan Chandrasekhar’s 107th Birthday in today’s GoogleDoodle!
Twinkle, twinkle little star, how I wonder what you are. Thanks to Subrahmanyan Chandrasekhar, we know! Today marks the 107th birthday of the first astrophysicist to win a Nobel Prize for his theory on the evolution of stars.
A child prodigy, Chandra published his first paper and developed his theory of star evolution before turning 20. By age 34, he was elected to the Royal Society of London, and soon after, became a distinguished service professor of physics.
The Indian-American physicist’s honors are astronomical, including the National Medal of Science, the Draper Medal of the US National Academy of Science, and the gold medal of the Royal Astronomical Society. Though originally met with skepticism in the 1930s, Chandra’s theories and equations won the Nobel Prize in Physics 50 years later.
Today’s Doodle illustrates one of the most important of all of S. Chandrasekhar’s contributions to our understanding of stars and their evolution: The Chandrasekhar limit. The limit explains that when a star’s mass is lighter than 1.4 times that of the sun, it eventually collapses into a denser stage called a white dwarf. When heavier than 1.4, a white dwarf can continue to collapse and condense, evolving into a black hole or a supernova explosion.
Today we honor the original starman whose universal theories propel current space research and modern astronomy on their ambitious missions.
Happy birthday, Chandra!

Awards and Honours
Nobel Prize in Physics
Chandrasekhar was awarded the Nobel Prize in Physics in 1983 for his studies on the physical processes important to the structure and evolution of stars. Chandrasekhar accepted this honor, but was upset the citation mentioned only his earliest work, seeing it as a denigration of a lifetime’s achievement. He shared it with William A Fowler. He is the first astrophysicist to have won a Nobel Prize.
