9320068 Lovelace There are important fundamental unsolved problems in astrophysics such as supernova explosions, formation and propagation of stellar and extragalactic jets, formation of stars and compact objects where rotation and magnetic fields are significant. A rigorous understanding of these rotating magnetized systems can be obtained only as a result of systematic development of one, two, and three dimensional magneto-hydrodynamical models and corresponding computer simulation codes. In this proposal the Principal Investigators plan to treat a number of astrophysical problems based partly on advanced 2D computer codes created at the M.V. Keldysh Institute of Applied Mathematics at Moscow University, and on codes developed at Cornell University. The collaboration of scientists at the Space Research Institute (IKI) in Moscow and Cornell began more than two years ago, and several joint papers have been published. They have now involved applied mathematicians in the project, and several computer codes have been created and successfully tested on small, personal computers in Russia and the U.S. However, to obtain the physically interesting results, much longer calculations on the larger computers and supercomputers are needed. This research will enhance the interactions between scientists in the U.S. and Russia and will lead to advances in our understanding of magneto- rotational phenomena in astrophysics which may have practical laboratory applications.

9320068 lovelace在天体物理学中存在重要的基本未解决的问题，例如超新星爆炸，恒星和静脉外喷气机的形成和传播，恒星的形成以及旋转和磁场很重要的恒星和紧凑物体。 对这些旋转磁化系统的严格理解仅是由于系统开发的结果，二维和三维磁力流动力模型和相应的计算机仿真代码的结果。 在该提案中，主要研究人员计划根据M.V.创建的高级2D计算机代码来治疗许多天体物理问题。 Keldysh应用数学研究所在莫斯科大学以及康奈尔大学开发的代码。 两年多前，莫斯科和康奈尔大学太空研究所（IKI）的科学家合作开始了，并发表了几篇联合论文。 他们现在已经参与了该项目的应用数学家，并且已经在俄罗斯和美国的小型个人计算机上创建并成功测试了几种计算机代码，但是为了获得物理上有趣的结果，需要在较大的计算机和超级计算机上进行更长的计算。 这项研究将增强美国和俄罗斯科学家之间的相互作用，并将在我们对可能具有实验室应用的天体物理学中的磁旋转现象的理解方面取得进步。
