  Chandrasekhar limit - Wikipedia, the free encyclopedia
The Chandrasekhar limit is the maximum mass of a white dwarf, and is approximately 3 × 10
The Chandrasekhar limit arises from taking account of the effects of quantum mechanics in considering the behaviour of the electrons providing the degeneracy pressure supporting the white dwarf.
In the quantum mechanical calculation the typical energies to which degeneracy pressure forces the electrons in a massive white dwarf are non-negligible relative to their rest masses and a limiting mass emerges for a self-gravitating, spherically symmetric body supported by degeneracy pressure.

Subrahmanyan Chandrasekhar (सुब्रह्मण्यन् चन्द्रशेगर) (October 19, 1910 – August 21, 1995) was an Indian - American physicist, astrophysicist and mathematician, who was awarded the 1983 Nobel Prize in Physics.
Chandrasekhar was the nephew of Nobel-prize winning physicist C.
He was awarded the Nobel Prize in Physics in 1983 for his studies on the physical processes important to the structure and evolution of stars, though he was upset that the citation mentioned only his earliest work, seeing this as a denigration of a lifetime's achievement.

 Subrahmanyan Chandrasekhar
Chandrasekhar was noted for his work in the field of stellar evolution, and in the early 1930s he was the first to theorize that a collapsing massive star would become an object so dense that not even light could escape it.
In addition to his work on star degeneration, Chandrasekhar contributed important theorems on the stability of cosmic masses in the presence of gravitation, rotation, and magnetic fields; this work proved to be crucial for the understanding of the spiral structure of galaxies.
From the time he came to the US in 1936 until his death in 1995, Chandrasekhar was affiliated with the University of Chicago and its Yerkes Observatory.
