Abstract

When the geometry of a cloud configuration is not spherical, long range property of gravity induces varies unexpected behavior. In many cases, therefore, simple consideration leads us to a wrong result on the problems of star formation. To obtain detailed feature of gravity in star formation, we studied numerically the behavior of gravity for rotating isothermal clouds. We constructed equilibrium models extensively, and studied the evolution of non-axisymmetric perturbation.
