Supernovae and Astrophysical Gas Dynamics

超新星是已知能量最大的恒星爆炸。 它们喷射出爆炸恒星的外壳（在许多情况下 质量是太阳的几倍）以一定的速度进入太空 从每秒1000公里到每秒10,000公里 喷出物 膨胀到周围的星际气体中，压缩它， 在许多情况下会导致星星的形成。 校长 研究者建议通过计算研究相互作用 超新星喷出物和星际气体之间的联系 他还 提议研究超新星爆炸的某些细节， 例如落在致密物体上的物质 在爆炸后。 此外，他建议使用相同的 超新星研究中使用的数值技术， 星系形成

Supernovae are the most energetic stellar explosions known. They eject the exploding stars' outer envelopes (in many cases having several times the mass of the sun) into space at speeds of several 1000 km/sec to a few 10,000 km/sec. The ejecta expand into the surrounding interstellar gas, compress it, and in many cases induce star formation. The Principal Investigator proposes to study computationally the interaction between supernova ejecta and the interstellar gas. He also proposes to study certain details of the supernova explosion, such as the matter falling onto the compact object remaining after the explosion. Further-more, he proposes to use the same numerical techniques used in the supernova study to investigate galaxy formation.
