论文摘要
在这项工作中，我们报告了在大约180和150 pc的太阳附近发现了2个新的恒星协会。这两个关联是根据$α$，$δ$，$μ_α$，$μ_δ$和$π$ gaia的聚类来检测的，称为U Tau Assoc和e tau合作。在其颜色数字图中，预序序模型等速线的拟合表明，这两个关联约为50 MYR，小组成员低于$ {\ sim} $ 0.8 $ M _ {\ odot} $，是在Tost-t Tauri的阶段。
In this work we report the discovery of 2 new stellar associations in close vicinity of the Sun at roughly 180 and 150 pc. These two associations, named as u Tau assoc and e Tau assoc, were detected based on their clustering in a multi-dimensional parameter space including $α$, $δ$, $μ_α$ , $μ_δ$ and $π$ of Gaia. The fitting of pre-main-sequence model isochrones in their color-magnitude diagrams suggests that the two associations are of about 50 Myr old and the group members lower than ${\sim}$0.8 $M_{\odot}$ are at the stage of post-T Tauri.
