"Dr. Chandrasekhar read a paper describing the research which he has recently carried out, an account of which has already appeared in The Observatory, 57. 373, 1934, investigating the equilibrium of stellar configurations with degenerate cores. He takes the equation of state for degenerate matter in its exact form, that is to say, taking account of relativistic degeneracy. An important result of the work-is that the life history of a star of small mass must he essentially different from that of a star of large mass. There exists a certain critical mass M. If the star's mass is greater than M the star cannot have a degenerate core, but if the star's mass is less then M it will tend, at the end of its life history, towards a completely collapsed state."
