| Research Abstract |
Using numerical simulation, the formation of stats and circumstellar disks in molecular cloud cores were investigated. In the collapsing cloud, the rotating disk appears. Then, the protostellar outflow is driven from the disk by the Lorentz force. The protostellar outflow ejects the gas inside the cloud into interstellar medium and suppresses the star formation rate to less than 50%.
