Abstract

The formation of protostars in magnetized rotating molecular cloud cores is investigated numerically. The simulations are carried out with the help of the 20 MHD-code ‘Moon’. This code is based on the total variation diminishing (TVD) difference scheme for the solution of the MHD equations. A simple classification of the self-gravitating MHD flows is presented. The possibility of molecular outflow and jet generation at the advanced stages of MHD collapse is discussed. The generation and initial evolution of jets around ‘zero’-age young stellar objects is considered as a separate problem.
