This is an observational project devoted to measuring the parallaxes of nearby low-mass stars in the Upper Sco and Chamaeleon I clusters. Low-mass stars, such as M0-M3 spectral types, are the focus because of their importance to stellar evolution and planet formation models, and because very few accurate distances are known for these spectral types, due to not being included in the Hipparcos mission and other surveys (due to being too faint for previous studies). The PI has obtained most of the necessary data and will use the CAPSCam at Las Campanas Observatory to get the rest of the observations.Broader impacts include training and mentoring a postdoctoral researcher, and undergraduate students participating in the Carnegie Summer Scholars program.

这是一个观测项目，致力于测量在Upper Sco和Chamaeleon I星团中附近低质量恒星的视差。 低质量恒星，如M0-M3光谱类型，是焦点，因为它们对恒星演化和行星形成模型的重要性，并且因为这些光谱类型的精确距离很少，因为没有包括在依巴谷使命和其他调查中（由于以前的研究太微弱）。PI已经获得了大部分必要的数据，并将使用Las Campanas天文台的CAPSCam来获得其余的观测结果。更广泛的影响包括培训和指导博士后研究人员，以及参加卡内基夏季奖学金计划的本科生。
