dc.descriptionDynamical contraction of a slowly-rotating magnetized cloud is studied using the magnetohydrodynamical (MHD) simulations. In the isothermal stage ($n \la n_{\rm A} \sim 10^{10}{\rm cm}^{-3}$), the cloud evolves similarly to that expected from Larson-Penston self-similar solution and experiences the run-away collapse. However, after the central density exceeds $\sim n_{\rm A}$, an accretion disk is formed around the adiabatic core. Just outside the core, outflow is ejected by the effect of magnetic torque (magnetocentrifugal wind). Since $\sim$ 10% of the mass is ejected with almost all the angular momentum, the specific angular momentum of the protostellar core reduces to that observed in main-sequence stars.
