What did Chandrasekhar discover?

Subrahmanyan Chandrasekhar was an astrophysicist. He discovered that massive stars can collapse under their own gravity to reach enormous or even infinite densities. Today we call these collapsed stars neutron stars and black holes.

What subject is Chandrasekhar best known for studying?

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.

What were Chandrasekhar contribution to the field of astrophysics?

Chandrasekhar determined what is known as the Chandrasekhar limit—that a star having a mass more than 1.44 times that of the Sun does not form a white dwarf but instead continues to collapse, blows off its gaseous envelope in a supernova explosion, and becomes a neutron star.

Why did Subrahmanyan Chandrasekhar get Nobel Prize?

The Nobel Prize in Physics 1983 was divided equally between Subramanyan Chandrasekhar “for his theoretical studies of the physical processes of importance to the structure and evolution of the stars” and William Alfred Fowler “for his theoretical and experimental studies of the nuclear reactions of importance in the …

Who gave black hole concept in India?

C. V. Vishveshwara (6 March 1938 – 16 January 2017) was an Indian scientist and black hole physicist. Specializing in Einstein’s General Relativity, he worked extensively on the theory of black holes and made major contributions to this field of research since its very beginning.

What is the Chandrasekhar limit of a white dwarf?

approximately 1.4 times
The Chandrasekhar Limit is now accepted to be approximately 1.4 times the mass of the sun; any white dwarf with less than this mass will stay a white dwarf forever, while a star that exceeds this mass is destined to end its life in that most violent of explosions: a supernova.

What did Chandrasekhar do in his first year at Cambridge?

In his first year at Cambridge, as a research student of Fowler, Chandrasekhar spent his time calculating mean opacities and applying his results to the construction of an improved model for the limiting mass of the degenerate star. At the meetings of the Royal Astronomical Society, he met E. A. Milne.
