ACCRETION OF INTERSTELLAR GAS BY A STAR IN THE PRESENCE OF RADIATION.

Abstract

Following the work of Bondi and McCrea, we have considered a point stationary star surrounded by an infinitely extending cloud of gas. The material in the cloud moves towards the star due to its gravitational force so that a spherically symmetrical steady  motion is established in the cloud and matter continually fals in the star.

The main contribution in this paper is the-inclusion of radiation effects through the adiabatic coefficient introduced by K limshin.
