RUI: Simultaneous Spectroscopy and Photometry of Interacting Binaries. A Joint Project with the University of Illinois.

大多数恒星都存在于二元系、三元系和更高阶系统中。双星系统中的一些恒星彼此如此接近，以至于它们强烈地影响着彼此的结构和演化。在这种相互作用的双星中，人们经常观察到一颗恒星到另一颗恒星的质量转移，接收质量的恒星周围的吸积盘，以及恒星大气和盘的加热和结构扭曲。首席研究人员建议在选定的一组相互作用的双星的情况下，利用同时测光和光谱分析来研究这些现象。将使用的仪器是一米长的伊利诺伊州反射镜，目前位于圣地亚哥以东50英里处的拉古纳山天文台，由圣地亚哥州立大学天文学系维护。这项工作将与伊利诺伊大学的爱德华·C·奥尔森博士合作进行。

The majority of stars occur in binary, tertiary, and still higher order systems. Some of the stars in binary systems are in such close proximity of each other that they strongly effect each other's structures and evolution. In such "interacting" binaries, one frequently observes mass transfer from one star to the other, an accretion disk around the mass receiving star, and heating and structural distortions of the stars' atmospheres and the disk. The Principal Investigator proposes to study these phenomena in the case of a selected group of interacting binaries, employing simultaneous photometry and spectroscopy. The instrument to be used will be the one-meter Illinois reflector that is now located at the Mount Laguna Observatory 50 miles east of San Diego and maintained by the Astronomy Department of the San Diego State University. The work will be carried out in collaboration with Dr. Edward C. Olson of the University of Illinois.
