This research project will continue and expand a vigorous program of research on questions related to binaries in dense stellar environments and close binary systems. The specific problems exhibit a range of difficulty. Some, like the influence of the interstellar medium on the observability of supersoft sources, are ones for which the relevant tools are rather easily available and can be completed relatively quickly. Others, like work on three- and four- body processes in globular clusters, require a good deal of study and work to lay proper foundations for the research proposed here. The work on mass stripping during tidal capture and circularization falls into this category. This is a broad research program, to be carried out over a two year period. There are interconnections between many of the questions to be explored, and previous work in all of these areas provides a strong lead-in for several of the problems. Interactive activities include teaching an astronomy course at the advanced undergraduate level, and a graduate course on galactic dynamics. Other activities involve: hosting a regional conference to address local needs regarding encouraging young women in the sciences (at the undergraduate level and above) to enthusiastically pursue their interest in science, and the possibility of networking and other strategies to enhance the effectiveness of existing local resources; and working with the Center for Astrophysics Women's Program Committee to design and participate in workshops for young women scientists at the Center.

这项研究项目将继续并扩大一项关于密集恒星环境和近距离双星系统中双星相关问题的研究计划。具体的问题表现出一系列的困难。其中一些，如星际介质对超软源可观测性的影响，是相关工具相当容易获得并可以相对较快地完成的。其他方面，比如球状星团中的三体和四体过程，需要大量的研究和工作，为这里提出的研究奠定适当的基础。关于潮汐捕获和环流过程中的物质剥离的工作就属于这一类。这是一个广泛的研究计划，将在两年内进行。要探索的许多问题之间存在着相互联系，所有这些领域以前的工作都为其中几个问题提供了强有力的先导。互动活动包括教授本科高级水平的天文学课程，以及关于星系动力学的研究生课程。其他活动包括：主办一次地区会议，以满足当地在鼓励科学领域的年轻女性(本科及以上)热情追求其对科学的兴趣方面的需求，以及建立网络和其他战略的可能性，以提高现有地方资源的有效性；以及与天体物理中心妇女计划委员会合作，设计并参加该中心为年轻女科学家举办的讲习班。
