论文摘要
通过GAIA DR3数据和先前的文献确认并描述了包含NGC 6871的开放群集的原始组。它是一种详细介绍和研究，其中详细介绍了和研究，它是一种至少有六个年轻OC的星形复合体，其中包括Teutsch 8，FSR 198和Biurakan 2。详细介绍和研究了附近的两个OC（Casado 82和Casado-Hendy 1）附近的两个OC（Casado 82和Casado-Hendy 1），并被详细识别并被发现也是引用组的成员。组件的参数足够相似，可以假定至少六个由单个GMC诞生的簇。该小组的群集对似乎都不是一个真实的二进制群集，除了候选对Teutsch 8/fsr 198的可能外，NGC 6871似乎正在瓦解，而原始组成员似乎很快分散了。使用GAIA数据搜索在年轻或分组OC附近的新开放群集是找到形成原始组的新相关OC的有效策略。
A primordial group of open clusters containing NGC 6871 is confirmed and described through Gaia DR3 data and the previous literature. It is a star-forming complex containing at least six young OCs, including Teutsch 8, FSR 198 and Biurakan 2. Two nearby OCs (Casado 82 and Casado-Hendy 1) are newly identified and studied in detail and found to be also members of the cited group. The parameters of the components are sufficiently similar to postulate the case of at least six clusters born from a single GMC. None of the cluster pairs of the group seems to be an authentic binary cluster, with the possible exception of the candidate pair Teutsch 8/FSR 198. Instead, NGC 6871 seems to be disintegrating, and the primordial group members appear to be dispersing out rapidly. Searching for new open clusters in the vicinity of young or grouped OCs using Gaia data is an efficient strategy to find new associated OCs forming primordial groups.
