The Star-Stream Interaction in Short-Period Algol-Type Binaries

天文学中一个长期感兴趣的研究课题是大流星类型的恒星系统。这些双星系统由一颗恒星组成，恒星的表层正在膨胀，并将物质转移到伴星。后一颗恒星吸积转移的物质。PI将从理论上研究质量增加恒星上吸积物质撞击区域的几何、动力学和热力学性质。此外，PI将测量她正在研究的两个ALGOL系统在H-Alpha线上发射的辐射。她将比较观测到的和理论上的谱线轮廓，以确定恒星周围物质在这些系统中的位置。

A research topic of long-standing interest in astronomy is that of Algol-type stellar systems. These binary systems consist of a star whose surface layers are expanding and transferring matter to a companion star. The latter star accretes the transferred matter. The PI will investigate theoretically the geometric, dynamic, and thermodynamic properties of the region on the mass- gaining star where the accreting matter impacts. Furthermore, the PI will measure the radiation emitted in the H-alpha line by two of the Algol systems she is studying. She will compare observed and theoretical line profiles in order to determine the location of circumstellar material in these systems.
