论文摘要
尽管以前对星团簇的搜索非常成功，但许多群集可能仍被省略，尤其是在高银河纬度地区。在这项工作中，基于Gaia EDR3的天体统计，我们在附近（视差> 0.8 MAS）的全套区域搜索，获得了886个星团，其中270名候选人以前没有被分类。同时，我们通过将理论异源拟合到其光学幅度来介绍簇的物理参数。还发现了许多恒星簇中更多的光晕成员和扩展的结构。大多数新物体都是年轻的群集，历史少于1亿年。我们的工作大大提高了太阳街区星团的样本量和物理参数，特别是在| b |的情况下，新发现了46个集群。 > 20度，这表示在高银河纬度区域的簇数增加了近三倍。群集参数和成员明星可通过https://cdsarc.u-strasbg.fr/ftp/ftp/ftp/fizier.submit//hezh22b/获得，并且可以通过https://doi.org/10.12149/101133获得群集图集。
Although previous searches for star clusters have been very successful, many clusters are likely still omitted, especially at high Galactic latitude regions. In this work, based on the astrometry of Gaia EDR3, we searched nearby (parallax > 0.8 mas) all-sky regions, obtaining 886 star clusters, of which 270 candidates have not been cataloged before. At the same time, we have presented the physical parameters of the clusters by fitting theoretical isochrones to their optical magnitudes. More halo members and expanding structures in many star clusters were also found. Most of the new objects are young clusters that are less than 100 million years old. Our work greatly increased the sample size and physical parameters of star clusters in the solar neighborhood, in particular, 46 clusters are newly found with |b| > 20 deg, which represents an increase of nearly three fold of cluster numbers at high Galactic latitude regions. The cluster parameters and member stars are available at CDS via https://cdsarc.u-strasbg.fr/ftp/vizier.submit//hezh22b/, and the cluster figure sets are available via https://doi.org/10.12149/101133.
