Abstract

In this paper early state star formation is investigated under three soft equations of state. The soft equations of state allow for the collapse to be followed to just beyond the isothermal limit - before the radiative pressure in the collapse becomes significant. A TVD Roe scheme is used to numerically solve the fluid equations modelling the collapse and the gravitational force is updated in place of the potential thus saving computational time. In the most extreme equation of state a distinct protostellar core is formed while the other two equations of state provide similar results. The occurrence of a rebound in the protostellar core together with the ensuing shock wave is briefly discussed.
