RUI: Radial Velocity Studies and Absolute Parameters of Stellar Contact Binary Systems

现在人们已经认识到，我们地球上超过50%的恒星 星系都是双星系统。 有些双星 接触双星，这意味着它们的大气层 并且两颗恒星强烈地相互作用（潮汐相互作用， 质量传递）。 首席研究员在报告中建议， 研究在本科院校（RUI）建议观察 一个相对均匀的接触双星样本， 决定1。它们的质量比、半径和光度 和2.测试当前的起源和进化理论， 这些系统。

It is now recognized that more than 50% of the stars in our Galaxy are in binary systems. Some of these binary stars are contact binaries, meaning that their atmospheres are in contact and that the two stars interact strongly (tidal interactions, mass transfer). The Principal Investigator proposes in this Research in Undergraduate Institutions (RUI) proposal to observe a relatively homogenous sample of contact binaries with the aim of determining 1. their masses ratios, radii, and luminosities and 2. testing current theories of the origin and evolution of these systems.
