How Young Stars Behave in Couples and the Impact on Binary Formation, Disk Evolution, and Planet Formation

这是一个致力于使用高分辨率光谱和红外波长成像技术测量100个年轻多恒星系统的恒星和盘状属性的观测项目，主要使用凯克天文台。她将使用这些数据来确定恒星的有效温度、径向速度、自转速度和表面重力，以及与周围磁盘材料相关的吸积率和磁场。这些数据将被用来测试行星系统和恒星周盘的双星形成和角动量分布模型。更广泛的影响包括培训一名博士后研究人员，以及更新一个网站，为社区建立一个视觉双星数据库。国际天文学协会还计划继续向当地的老年中心介绍天文学。

This is an observational project devoted to measuring stellar and disk properties for a hundred young multiple star systems using high-resolution spectroscopy and imaging techniques at infrared wavelengths, mainly using Keck Observatory. She will use the data to determine effective temperatures, radial velocities, rotation rates and surface gravities of stars, as well as accretion rates and magnetic fields associated with surrounding disk material. The data will be used to test models of binary formation and angular momentum distribution of planetary systems and circumstellar disks. Broader impacts include training a postdoctoral researcher, and updating a website with a database on visual binary stars for the community. The PI also plans to continue giving astronomy presentations to local senior centers.
