Subrahmanyan Chandrasekhar was born in 1910 in India. He received his early education in India and received his PhD from Cambridge University in 1933. In 1930, he discovered the Chandrasekhar limit, which established the maximum mass that can be supported by the pressure of electrons in a white dwarf star. This discovery led to the later discoveries of neutron stars and black holes. Throughout his career, Chandrasekhar made seminal contributions to the fields of stellar structure and evolution. He was awarded the Nobel Prize in Physics in 1983 for his work on stellar structure and evolution. Chandrasekhar passed away in 1995 at the age of 84.

5. In 1930, he showed that there is a maximum mass
which can be supported against gravity by pressure made
up of electrons and atomic nuclei . The value of this limit is
about 1.44 times of solar mass .If the mass of a star exceeds
the limit, the star would not become a white dwarf .The
formulation of the Chandrasekhar limits led to the
discovery of neutron stars and black holes. Depending on
the mass there are 3 final stages of a star–white dwarf,
neutron star & black hole . Chandrasekhar was awarded the
Nobel Prize in Physics in 1983.
Subrhamanyan Chandrasekhar is best known for his
discovery of Chandrasekhar Ltd.

by Subrahmanyan Chandrasekhar includes:
1.Stellar structure including the theory of white dwarf
( 1929-39)

7. 2.Stellar dynamics, including the theory of Brownian
Movement and motions(1938-43)

8. 3. The theory of radioactive transfer,

ellipsoidal figures of equilibrium
(1961-68)
6. The general theory of relativity
and relativistic astrophysics
(1962 -71)

11. 7.Theory of black holes(1974-83)

12. NOBEL PRIZE
Awarded Nobel prize in Physics in 1983. for his studies on
the physical process important to the structure and
evolution of stars.
He accepted this honor, but was upset the citation
mentioned only his earliest work, seeing it as a denigration
of a life time’s achievement.
