AST-9702908 Abstract - J. Blondin Computers have made an important impact on both astrophysics research and education over the last several years. Numerical simulations on modern supercomputers have made great strides in our ability to do research in virtually every subfield of astrophysics, from computing chaotic planetary orbits to the models of the formation of large-scale structure in the Universe. At the same time, computers have become an ever-growing presence in our nation's classrooms. Now, with the increasing popularity of the World Wide Web, those computers are opening up the classroom to the world. This is a project to exploit this natural link between computational astrophysics and computer- based education. The educational aspect of this project will draw on a variety of different avenues, including the development of a new, computer- based astronomy lab at NCSU for non-science undergraduates, the creation of web sites intended to convey the excitement of current astrophysics research to the general public by drawing on the visually striking results of numerical simulations, the teaching on numerical methods in upper-level physics courses, and the involvement of undergraduates in computational astrophysics research. The research aspect of this project will focus on the hydrodynamics of mass and angular momentum transfer in X-ray binary stars. However, this work will have far reaching impact, for the phenomenon of mass transfer is an important process in a wide range of binary star systems. By studying X-ray pulsars, where one has a quantitative measure of both the mass and angular momentum accretion rate, one can learn about the physics of Roche lobe overflow, tidal stream impact, accretion disk formation, disk winds, and much more. Furthermore, the current wealth of observational data from satellites such as ASCA, BATSE, and XTE will greatly accelerate the progress in this fi eld over the next few years, and the numerical models generated in the proposed research will provide an important key to interpreting this new data.

AST -9702908摘要-J。金发计算机在过去几年中对天体物理学研究和教育产生了重要影响。对现代超级计算机的数值模拟在我们在天体物理学的几乎每个子场进行研究的能力取得了长足的进步，从计算混乱的行星轨道到宇宙中大规模结构的形成模型。 同时，计算机在我们国家的教室中不断增长。现在，随着万维网的日益普及，这些计算机正在向世界开放教室。 这是一个项目，旨在利用计算天体物理学和基于计算机的教育之间的这种自然联系。 该项目的教育方面将借鉴各种不同的途径，包括在NCSU上开发一个新的，基于计算机的天文学实验室，用于非科学本科生，创建网站的创建，旨在通过在涉及数字的涉及数字的涉及数字的基础上，以绘制涉及数字的涉及数值的兴奋，以将当前天体物理学研究的激励传达给公众，并在数字上均具有数值的教学。计算天体物理学研究的大学生。 该项目的研究方面将集中于X射线二元星中质量和角动量转移的流体动力学。但是，这项工作将产生很大的影响，因为传质现象是广泛的二元星系中的重要过程。通过研究X射线脉冲星，其中一个人对质量和角动量吸积率都具有定量度量，可以了解Roche Lobe溢出，潮汐流撞击，增生盘形成，磁盘风，风能等的物理。此外，当前来自ASCA，BATSE和XTE等卫星的观测数据将在未来几年中大大加速这一FI的进度，并且在拟议的研究中生成的数值模型将为解释这一新数据提供重要的关键。
