中文摘要
这是一个观测项目,主要利用凯克天文台,利用高分辨率光谱学和红外波长成像技术,专门测量100个年轻的多星星系统的恒星和星盘特性。她将利用这些数据来确定恒星的有效温度、径向速度、旋转速率和表面重力,以及与周围圆盘材料相关的吸积速率和磁场。 这些数据将用于测试行星系统和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,并更新一个网站,为社区提供关于可视双星的数据库。PI还计划继续向当地高级中心提供天文学报告。
英文摘要
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.
