论文摘要
本工作的目的是对Collinder 135和UBC 7星簇的动力学进化的详细研究。我们提供了一组动态数值仿真，从而，基于最佳可用的3D坐标和从最新的Gaia EDR3数据释放中获得的最佳3D坐标和速度，从而将逐个星形群集模型的正向整合到当今今天。我们已经确定Collinder 135和UBC 7可能是二进制星团，并且具有共同的起源。我们使用单个恒星进化的新算法对两个集群的恒星种群进行了完整的逐星n身体模拟，并对观察数据中获得的结果（例如累积数量计数）进行了比较，这表明表现出了相当良好的一致性。
The purpose of the present work is a detailed investigation of the dynamical evolutionof Collinder 135 and UBC 7 star clusters. We present a set of dynamical numerical simulationsusing realistic star clusterN-body modeling technique with the forward integration of thestar-by-star cluster models to the present day, based on best-available 3D coordinates and velocitiesobtained from the latest Gaia EDR3 data release. We have established that Collinder 135 and UBC 7 are probably a binary star cluster and have common origin. We carried out a full star-by-star N-body simulation of the stellar population of both clusters using the new algorithm of Single Stellar Evolution and performed a comparison of the results obtained in the observational data (like cumulative number counts), which showed a fairly good agreement.
