论文摘要
我们使用pyupmask和HDBSCAN聚类算法基于{\ it Gaia} dr3,系统地搜索了500 pc内太阳能社区中的开放群集。考虑到大多数开放簇的物理尺寸少于50 pc,我们采用了一种切片方法,用于不同的距离壳,并确定了324个相邻的开放式簇,包括223个报告的开放式群集和101个新发现的开放式群集(称为OCSN,命名为OCSN,Solar Solar of Solar egriebore)。我们的发现使太阳能社区中的开放簇数量增加了约45%。在这项工作中,我们的群集样本获得了较大的空间扩展和更多的成员恒星。我们为每个群集提供了通过pyupmask算法提供成员恒星和成员概率,并得出了它们的天体物理,年龄和结构参数。
We systematically searched for open clusters in the solar neighborhood within 500 pc using pyUPMASK and HDBSCAN clustering algorithms based on {\it Gaia} DR3. Taking into consideration that the physical size for most open clusters is less than 50 pc, we adopted a slicing approach for different distance shells and identified 324 neighboring open clusters, including 223 reported open clusters and 101 newly discovered open clusters (named as OCSN, Open Cluster of Solar Neighborhood). Our discovery has increased the number of open clusters in the solar neighborhood by about 45\%. In this work, larger spatial extents and more member stars were attained for our cluster sample. We provided the member stars and the membership probabilities through the pyUPMASK algorithm for each cluster and derived their astrophysical, age, and structural parameters.
