Today (October 19, 1910) is the birthday of Nobel Prize-winning Indian physicist Subramanian Chandrasekhar, who discovered that a small star could explode and form a bright 'supernova'.
Subrahmanyan Chandrasekhar was born on October 19, 1910 in Lahore, Punjab, India (now Pakistan) to C. Subramanian Iyer and Sita Lakshmi Amma. His father worked as a government official. Subramanian Chandrasekhar's family moved to Chennai after spending five years in Lahore and two years in Lucknow. He attended the Hindu High School at Tiruvallikeni in Chennai and later pursued his higher education at the State College and obtained his BA in Physics from the same college. It was during this time in 1928 that his uncle Sir C.V. Rama received the Nobel Prize.
In 1928, when Arnold Sommerfeld came to India, he lectured at the State College in Chennai. Chandrasekhar, who had already read his book, met him and learned about the new research that had taken place in physics and paid close attention to reading books about them. As a result, he published his first research paper the following year. A lecture similar to this article was given at the Indian Science Conference in Chennai that year with the admiration of senior scientists, and his research journey began successfully. Also, the following year at the age of 19, while still an undergraduate, two more articles were published. In 1930, with the gift and financial assistance of the Government of India, Chandrasekhar traveled to Cambridge University for further studies.
Professor R. H. He continued his
research work as a research student under Fowler, earning a doctorate in 1933
from the University of Cambridge. He later became a research professor at
Trinity College, where he met Arthur Eddington, a world-renowned astronomer. He
was excited to have the opportunity to interact with his favorite researcher.
Later, he returned to the UK and continued his research work, publishing
numerous research papers on the structure of galaxies, as well as specializing
in various areas of his research. Then, in 1937, he was sought by astronomers
at the University of Chicago in the United States. He happily traveled to the
United States to continue his work, educating students and continuing his
research.
Chandrasekhar was very interested
in physics and space science. He excelled in it. He made a definition of the
weight of stars in astronomy. The star, which is 1.4 times the mass of the Sun,
was found to lose its stability. It is called the Chandrasekhar Limits. He
discovered that as the white small star weighed more, its nucleus would explode
like a 'nuclear bomb' and form bright 'supernova' stars. He discovered how
stars in the Milky Way share the movement of objects. Through this it was
possible to understand the ecosystem of the stars. And discovered why the sky
is blue.
In addition to being a
well-respected professor at the University of Chicago, he published a book
entitled "The Structure of the Stars" which summarizes his research
so far. He has also published numerous articles on astronomy, earning him
awards and medals from various countries. In 1983, he and William Fowler were
awarded the Nobel Prize in Physics for their research on galaxies, taking him
to the pinnacle of fame.
While working as an astronomer at
the University of Chicago in the United States, he married Lalita, who had
studied with him at Presidency College when he came to India. While studying,
he was a suitable companion in marriage because they were well acquainted and
was the impetus for his research. Subramanian Chandrasekhar, the Nobel
Prize-winning Indian physicist, passed away on August 21, 1995 at the age of 84
in Chicago, USA.
