Magneto-turbulent star formation with adaptive mesh refinement

采用自适应网格加密方法研究了磁湍流分子云核的引力坍缩。模拟结果表明，云核的低密度区受到湍流的扰动。高密度区域分别为低质量云核和高质量云核呈现盘状和丝状。在所有情况下，第一个核心都在云核心中形成，并在那里喷出外流。流出分为两种类型：双极流和螺旋流。

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.
