Corralling Young Stars

这项提议的目标是为天文学界提供一个全面的附近年轻恒星天体目录。目前，在距离太阳约800%的范围内，大约有1万到3万颗年轻恒星天体的数据分散在各种档案和已发表的文献中。这些包括年轻星团、星团和分子云中的恒星，具有以下一种或多种波长的光度/光谱数据：x射线、光学、近红外、中红外和亚毫米/毫米。此外，还可以通过各种资源获得恒星参数、角动量指标、活动度量、星周盘诊断等派生量。该项目将提供有针对性和灵活的基本数据产品，以及与年轻明星有关的高级数据产品，通过一个由所有已知或疑似人口成员的数据组成的关系数据库。该数据库还将具有广泛的教育价值，对从课堂上的教师到经验丰富的科学研究人员的广泛用户都很有用。

The goal of this proposal is to provide a comprehensive catalog of nearby young stellar objects fully accessible to the astronomical community. At present, data regarding the approximately 10,000 - 30,000 young stellar objects within ~800pc of the Sun are scattered throughout various archives and the published literature. These include stars in young clusters, associations, and molecular clouds, with photometric/spectroscopic data in one or more of the following wavelengths: x-ray, optical, near-infrared, mid-infrared, and sub-millimeter/millimeter. In addition, derived quantities such as stellar parameters, angular momentum indicators, activity measures, circumstellar disk diagnostics, etc. are also available through various resources. The project will provide targeted and flexible access to basic data products, as well as higher level data products that are relevant to young stars through a relational database populated with data from all known or suspected members of the population. The database will also have broad educational value useful to a wide spectrum of users from teachers in the classroom to experienced scientific researchers.
