The problem of star formation is presently actively studied both observationally and theoretically. The Principal Investigator proposes to model numerically the collapse of a protostellar cloud into a young stellar object, using 3-dimensional hydrodynamics. The goal is to improve on the existing sets of calculations of this kind by making the physics more realistic: including magnetic effects in the starting models, mass loss through stellar winds, and rotational instabilities. He also proposes to improve the spatial resolution and numerical accuracy of the calculations.

恒星形成问题目前在观测和理论上都得到了积极的研究。首席研究员建议用三维流体力学的方法对原恒星云坍缩成年轻恒星物体的过程进行数值模拟。目标是通过使物理更加真实来改进现有的这类计算集：包括初始模型中的磁效应，恒星风造成的质量损失和旋转不稳定性。他还建议提高计算的空间分辨率和数值精度。
