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.

小行星9320068 在天体物理学中有一些重要的基本问题尚未解决，如超新星爆炸，恒星和河外喷流的形成和传播，恒星和致密天体的形成，其中旋转和磁场是重要的。 这些旋转磁化系统的一个严格的理解，可以得到只有作为一个，两个和三维磁流体动力学模型和相应的计算机模拟代码的系统开发的结果。 在这项提议中，主要研究人员计划部分基于莫斯科大学M.V. Keldysh应用数学研究所创建的高级2D计算机代码和康奈尔大学开发的代码来处理一些天体物理问题。 莫斯科空间研究所（伊基）和康奈尔大学的科学家们的合作始于两年多前，并发表了几篇联合论文。 他们现在已经让应用数学家参与到这个项目中，并且已经创建了几个计算机代码，并在俄罗斯和美国的小型个人计算机上成功测试，然而，为了获得物理上有趣的结果，需要在大型计算机和超级计算机上进行更长的计算。 这项研究将加强美国和俄罗斯科学家之间的互动，并将导致我们对天体物理学中磁旋转现象的理解的进步，这可能具有实际的实验室应用。
