Evolution of large scale outflows from collapsing molecular cloud cores

Daniel Seifried

We plan to discuss the collapse of low and high mass, rotating and magnetized molecular cloud cores. The combined effect of rotation and magnetic fields leads to the occurrence of outflow phenomena. Our special interest lays in the long term evolution of large scale outflows appearing already in the early phase of stellar evolution. These outflows seem to release a significant amount of mass into the ambient medium and therefore reduce the rate of accretion onto the protostar. We are following the long term evolution of these outflows with the help of sink particles. With this technique we are able to examine whether magnetic towers and protostellar jets are persistent or just transient features. In the former case outflows should be able to open channels of low density gas through which radiation can escape. We are also planning to combine these MHD simulation with radiation transfer to address this question in more detail.
