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

天文学长期以来的一个研究课题是， 大陵五型恒星系统 这些二元系统由一个 表面层不断膨胀并转移物质的星星 一颗伴星星星。 后一颗星星吸积转移的 所谓了 PI将从理论上研究几何， 动力学和热力学性质的区域上的质量- 在吸积物质撞击的地方获得星星。 此外，委员会认为， PI将通过以下方式测量H-α线中发射的辐射： 两个她正在研究的大陵五星系 她会比较 观察到的和理论上的线轮廓，以确定 在这些系统中的拱星物质的位置。

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.
