Gravitational Prof. Chandrasekhar then illustrated the importance of general relativity for the late stages in the life of a typical massive star of say collapse and the twenty solar masses. Two very important features are, (0 the high degree of central condensation (with the central density as high problem of as a billion times the mean density) and {ii) the dominance of radiation pressure. In the singularities in Newtonian theory such a star is stable against a small radial disturbance. The adiabatic exponent (ratio of fractional small pressure general relativity change to fractional density change) is greater than the critical value of 4/3. When such a star is one hundred thousand times its Academy lecture given by Prof. Schwarzschild radius, general relativity is of no S Chandrasekhar on November 21, 1984 importance in determining its structure but has at the International Symposium on a profound effect on its stability and in fact the star can become unstable to grpwing radial Theoretical Physics in honour of SN Bose. oscillations.

Professor Suri Bhagavantam, a Foundation Fellow of the Academy, and a close associate of Professor C V Raman for over four decades, completed seventy five years on October 14, 1984.
