Subrahmanyan Chandrasekhar
1910 – 1995 · India · Astronomy, Physics, Mathematics
Nobel Prize in Physics, 1983
Worked out at nineteen why some stars must collapse into black holes.
Summary1,3,4
On a boat from Madras to Cambridge in 1930, Chandrasekhar calculated that a white dwarf above about 1.4 solar masses cannot support itself — it must keep collapsing. Eddington publicly ridiculed the result; it was vindicated decades later and won the Nobel Prize in 1983.
Achievements1,3,5
- Derived the Chandrasekhar limit (~1.4 solar masses) at age 19
- Provided the theoretical basis for neutron stars and black holes
- Wrote definitive monographs on stellar structure, radiative transfer, hydrodynamic stability and black-hole mathematics
- Edited the Astrophysical Journal for 19 years, turning it into the field's leading publication

How the work shapes the world today2,5
The Chandrasekhar limit is why Type Ia supernovae detonate at a consistent brightness — which is how astronomers measured cosmic acceleration and inferred dark energy, the biggest open problem in physics. NASA's Chandra X-ray Observatory, which images black holes and hot gas across the universe, carries his name. His treatment by Eddington is a standard case study in how scientific establishments suppress inconvenient results.
Posterity and the family line5
He married Lalitha Doraiswamy, a fellow physics student from Madras; they had no children and were married for 59 years.

Attested
Every link carries its own evidence. Documented means a register, will, archive or prize record names the relationship; attested rests on scholarly reference; contested is disputed between sources; and where the record runs out it is marked rather than filled in.
