Mass Transfer and Magnetic Activity in Eclipsing and Non- Eclipsing Algol Binaries

理查兹博士将继续她在紧密相互作用的双星系统中的传质研究。她将分析大量不同波长的大人马座双星的观测数据，包括紫外线、可见光和射电光谱，以及红外测光，这些数据通常是在同步观测活动中进行的。各种各样的技术被用来研究这些系统中的传质，包括研究线强度的轨道变化，分析发射在不同剖面上的径向速度变化，以及多普勒断层扫描来产生二元的重建图像。PI还将继续通过二维和三维流体动力学模拟来研究Algol系统，以帮助解释多普勒断层扫描图。研究的最终目标是确定algol的传质速率范围，并在选定的磁活性系统中，研究磁场如何影响双星的传质过程和演化。＊＊＊

Richards, Mercedes AST 96-18461 Dr. Richards will continue her studies of mass transfer in close interacting binary systems. She will analyze a large amount of observational data on Algol binaries at a variety of wavelengths, including spectroscopy in the ultraviolet, visible, and radio, and photometry in the infrared, often in simultaneous observation campaigns. A variety of techniques are used to investigate the mass transfer in these systems including study of the orbital variation of line strengths, analysis of the radial velocity variation of the emission in difference profiles, and Doppler tomography to produce reconstructed images of the binary. The PI will also continue studies of Algol systems through two- and three- dimensional hydrodynamic simulations to aid in the interpretation of the Doppler tomography maps. The ultimate goal of the research is to determine the range of mass transfer rates in Algols, and, in selected magnetically active systems, to study how magnetic fields influence the mass transfer process and evolution of the binary. ***
