description Subrahmanyan Chandrasekhar Overview

Subrahmanyan Chandrasekhar was an Indian-American theoretical physicist renowned for his groundbreaking work in astrophysics. His calculations established the Chandrasekhar Limit, defining the maximum mass a white dwarf star can sustain before collapsing. This pivotal discovery fundamentally altered our understanding of stellar evolution and earned him the Nobel Prize in Physics in 1983. Chandrasekhar’s research remains crucial for astronomers and physicists studying the properties and behavior of stars throughout their lifecycles.

help Subrahmanyan Chandrasekhar FAQ

What is the Chandrasekhar limit?

The Chandrasekhar limit is the maximum mass a stable white dwarf can have before it must collapse under gravity. It is usually given as about 1.4 times the mass of the Sun.

Why was Subrahmanyan Chandrasekhar's white dwarf work controversial?

Chandrasekhar's calculations challenged the idea that all white dwarfs could remain stable forever. Arthur Eddington publicly resisted the implication that massive stars could collapse, but Chandrasekhar's result later became central to modern astrophysics.

Did Chandrasekhar win the Nobel Prize?

Yes. Subrahmanyan Chandrasekhar shared the 1983 Nobel Prize in Physics with William A. Fowler for work on the structure and evolution of stars.

Where did Chandrasekhar work for most of his career?

Chandrasekhar spent most of his career at the University of Chicago. He was also closely associated with The Astrophysical Journal, serving as its editor for many years.
