Subrahmanyan Chandrasekhar was one of the greatest astrophysicists in the world. He is best known for the Chandrasekhar Limit and won the Nobel Prize in Physics in 1983.

Early Life of Subrahmanyan Chandrasekhar

Subrahmanyan Chandrasekhar was born on 19 October 1910 in Lahore. He came from an educated family and was the nephew of Nobel Prize-winning physicist C. V. Raman.

From a young age, he showed a strong interest in science and mathematics.

Education and Scientific Journey

He studied at Presidency College, Chennai and later went to Cambridge University in England.

During his journey to England, he began working on ideas that later became the famous Chandrasekhar Limit.

He later worked at the University of Chicago and made many important scientific contributions.

What is the Chandrasekhar Limit?

The Chandrasekhar Limit explains the maximum mass a star can have before it collapses.

  • If a star is small → it becomes a white dwarf
  • If it is larger than 1.4 times the Sun → it collapses
  • This collapse can form a neutron star or black hole

This discovery changed how scientists understand the life cycle of stars.

Nobel Prize in Physics (1983)

Subrahmanyan Chandrasekhar was awarded the Nobel Prize in Physics in 1983 for his research on the structure and evolution of stars.

His work helped scientists understand how stars change over time and how black holes are formed.

Contributions to Astrophysics

1. Study of Stars

He explained how stars are born, evolve, and die.

2. Black Hole Theory

His research helped scientists understand black holes better.

3. Mathematical Physics

He used mathematics to solve complex problems in astrophysics.

4. Scientific Research

He wrote many important books and research papers.
