Angular Momentum Transport in Primordial Star Formation

The angular momentum of a molecular cloud core is orders of magnitude larger than the angular momentum of a star. Clearly angular momentum must be lost or redistributed during the star formation process. Here we report the results from three dimensional, SPH simulations of a rotating self-gravitating primordial molecular cloud. Interestingly the angular momentum profile follows the characteristic power-law even though for different initial condition. We have shown the evolution of gravitational and hydrodynamical torque for the change of angular momentum during star formation. We further attempt to understand the dynamics of gas particle and the effect of radial gravitational acceleration on angular momentum transport during collapse. We also discuss the mass accretion phenomenon that might be related to the evolution of angular momentum during the formation of primordial protostar.
