| Research Abstract |
Gravitational collapse of magneto-turbulent molecular cloud cores is investigated by adaptive mesh refinement simulations. The simulations show that low-density regions of the cloud cores are disturbed by the turbulence. The high-density regions assume disk and filament shapes for low and high mass cloud cores, respectively. For all the cases, a first core is formed in the cloud core, and an outflow is ejected there. The outflows are classified into two types : bipolar and spiral flows.
