Chandrasekhar, Subramanyan (1910-1995) Indian astrophysicist who studied at Cambridge then moved to America and the University of Chicago. He has contributed significantly to many disparate branches of physics, including rotational figures of equilibrium, stellar interiors, black holes, radiative transfer, hydromagnetic stability, stellar dynamics, and many others. Chandrasekhar's name is immortalized in connection with the Chandrasekhar limit, which is the largest mass a white dwarf can…
The Chandrasekhar Limit is named for this man, who calculated it at age 19. It is the maximum mass of a white dwarf (~1.44 times the mass of the sun). If a white dwarf exceeds this mass, it wil explode as a supernova.
Subrahmanyan Chandrasekhar, is a Noble Prize winning Astrophysicist, who played a key role in our understanding of the structure and evolution of stars. Chandrasekhar limit, which specifies the maximum mass of a stable white dwarf star, is named after him to honour his contribution. He correctly predicted the existence of black holes and white dwarfs long before their observational discovery. Via @TheBetterIndia
Artistic rendering of RS Ophiuchi, a binary system in the constellation Ophiochus. This system is made up of a red supergiant and a white dwarf orbiting each other in close range. Matter lost from the red supergiant is constantly piling up on the white dwarf, and about every 20 years, the dwarf experiences a nova, blowing off this accumulated material. If it ever reaches a size of 1.4 Solar masses, or the Chandrasekhar limit, the white dwarf may perish in a type 1a supernova.
