RUI: Eclipsing Binary Stars as Astrophysical Laboratories

小行星9315365 有几类特殊的食双星，它们的轨道和物理性质非常适合作为天体物理实验室，既可以研究恒星本身，也可以研究它们所在的星系。 该项目的目的是提供有关星星系统的基本信息：组成恒星的内部结构、氦丰度、对流核心中过冲的影响、近心轴运动的广义相对论组成部分、恒星的性质以及到大麦哲伦云和小麦哲伦云的距离模数。 该奖项是在NSF的本科院校研究（RUI）计划的赞助下颁发的。

9315365 Guinan There are several special classes of eclipsing binary stars whose orbital and physical properties are well suited for them to serve as astrophysical laboratories, both for the study of the stars themselves and the galaxies in which they reside. The aim of this project is to provide essential information from binary star systems concerning: the internal structure of the component stars, the helium abundance, the effect of overshooting in the convective cores, the General Relativistic component to apsidial motion, and the properties of stars and the distance moduli to the Large and the Small Magellanic Clouds. This award is made under the auspices of the Research in Undergraduate Institutions (RUI) program at the NSF.
