Timeline

How the scientific journey developed

1910

Born in Lahore

Born into a scholarly family, Chandrasekhar showed early strength in mathematics and physics.

1930

Voyage to Cambridge

On his journey to England, he began calculations on relativistic electron degeneracy in dense stars.

1931–1935

Chandrasekhar limit

He showed that white dwarfs above a critical mass cannot remain stable, challenging prevailing ideas about stellar evolution.

1937

University of Chicago

He moved to the United States and built a long research career spanning stellar dynamics, radiative transfer and relativity.

1950s–1970s

Broad theoretical work

His books and papers shaped multiple branches of astrophysics and mathematical physics.

1983

Nobel Prize in Physics

He shared the Nobel Prize for theoretical studies of the physical processes important to stellar structure and evolution.

Defining Contribution

The mass limit that changed how we understand the death of stars

Chandrasekhar showed that electron degeneracy pressure can support a white dwarf only up to a critical mass of about 1.4 times the Sun’s mass. Beyond that, a star must undergo further collapse, opening the theoretical path toward neutron stars and black holes.
