U.S.-China Cooperative Research (Astronomy): Hydrodynami- cal Process in Binary Star Systems

该奖项旨在资助中美两国在理论天体物理学方面的合作研究。西北大学的罗纳德·塔姆博士和中国南京紫金山天文台的王德宇教授将在这笔拨款下共同研究相互作用的双星系统，这些系统已被证明是高能和偶尔高度瞬态活动的场所。具体来说，这项研究将集中在薄吸积盘的动力学不稳定性上。本项目由国家自然科学基金委员会和中国科学院根据1980年签署、1986年续签的《基础科学合作议定书》共同资助。

This award provides funds to support cooperative research in theoretical astrophysics between the United States and China. Dr. Ronald Taam of Northwestern University and Professor Wang Deyu of the Purple Mountain Observatory, Nanjing, China, will work together under this grant to investigate interacting binary star systems, which have been demonstrated to be sites of energetic and occasionally highly transient activiity. Specifically, this study will focus on dynamical instabilities in thin accretion disks. This project is jointly sponsored by the National Science Foundation and the Chinese Academy of Sciences under the Protocol on Cooperation in Basic Sciences signed in 1980 and renewed in 1986.
