Star Formation in Galaxies

电话：95-28424 Tohline博士将使用先前开发的引力流体动力学代码研究恒星形成。 具体来说，他将解决三个问题-映射出原恒星吸积盘变得动态不稳定的引力碎片的临界状态，检查椭球或哑铃形的平衡结构与非平凡的内部运动的动态稳定性，并研究翘曲HI星系盘的演化，以确定盘沉降过程与全球星星形成过程的联系程度。 ***

Tohline 95-28424 Dr. Tohline will study stellar formation using the gravitational hydrodynamics code developed previously. Specifically, he will address three problems -- to map out the critical states at which protostellar accretion disks become dynamically unstable to gravitational fragmentation, to examine the dynamical stability of ellipsoidal or dumbbell-shaped equilibrium structures with nontrivial internal motions, and to examine the evolution of warped HI galaxy disks to determine the extent to which the disk settling process is connected to the global process of star formation. ***
