The Collapse of Interstellar and Intergalactic Gas Clouds

Abstract

The problem covered by this contract was that of star formation through the collapse of interstellar gas clouds under their own self- gravitation. This is not a new idea in the field of star formation as the idea can be traced back at least as far as Laplace. However, the problem had only been considered for simplified conditions which were unrealistic, and which probably in no small measure contributed to two of the major difficulties (fragmentation and angular momentum) encountered by the theory. The aim of the present work was to apply numerical methods to the problem to find out if the ability to take account of more complex situations could alter the situation.
