Protostellar collapse with RHD in spherical symmetry

Abstract

We present a numerical radiation hydrodynamic calculation in multifrequency applied to the protostellar collapse. The past works which calculated collapse of protostellar clouds were based on the assumptions such as isothermal condition, the diffusion approximation and/or the grey approximation. On the contrary, our calculation requires none of them. As a test case, we calculated the collapse of a 1M_o homogeneous cloud.
