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. Mon. Not. Roy. Ast. Soc. 93:61-90, 1932 First to suggest neutrons in the interior of cold degenerate bodies by inverse beta decay Neutrons, degeneracy and white
dwarfs. Proc. Roy. Soc. A. 162:521-8, 1937 Derived a relation for the degree of ionization in the non-relativistic degenerate matter using virial theorem The theory of pressure-ionization
and its applications. Proc. Roy. Soc. A. 165:486-500, 1938 Determined the electrical and
thermal conductivities of dense degenerate matter Determined the energy generation in
degenerate matter due to H-H reaction Named non-degenerate radiation With B.N. Singh. Bose-Einstein statistics and degeneracy. Proc. Roy. Soc. A. 178:135-52, 1941 |
