Daulat Singh Kothari, Indian astrophysicist (Udaipur, Rajasthan 06 July 1906 – Udaipur, Rajasthan 21 February 1993) ACHIEVEMENTS Showed that atoms can be ionized by the application of pressure alone First to appreciate the importance of pressure ionization and relative importance of conduction and radiation in transport of energy in stars Proved that the size of a cold body could not exceed that of Jupiter Showed that the energy flow in the degenerate stellar colors is mainly by the thermal conduction Application of degenerate statistics to stellar matter.
