中文摘要
用数值模拟方法研究了分子云核中星盘和星周盘的形成。在坍缩的云团中,出现了旋转的圆盘。然后,原恒星外流被洛伦兹力从盘驱动。原恒星外流将星云内的气体蒸发到星际介质中,并将星星的形成率抑制在50%以下。
英文摘要
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%.
