论文摘要
本文提供了新的轨道目录及其参数，以根据目前已知的银河球状簇（GC）的完整列表，该列表由Vasiliev（2019）基于其速度和位置的最准确的现代测量。使用从GAIA EDR3目录（Vasiliev和Baumgardt，2021）获得的新的平均适当动作（2021）和新的平均距离（Baumgardt and Vasiliev，2021），在Spherric thrge的潜能中，将152个球状簇的轨道集成5吉尔向后进行5吉尔。 Navarro-Frank-White Halo（Bajkova和Bobylev，2016年）。将新的轨道参数与我们较早构建的轨道参数（Bajkova和Bobylev，2021）在相同的重力潜力中使用从Gaia DR2目录（Vasiliev，2019年）获得的适当运动以及与Harris Catalog Catalog（2010）的距离进行了比较。
This paper provides a new catalog of orbits and their parameters for a practically complete list of currently known galactic globular clusters (GCs), compiled by Vasiliev (2019) based on the most accurate modern measurements of their velocities and positions. The integration of the orbits of 152 globular clusters for 5 Gyr backward was performed using the new average proper motions obtained from the Gaia EDR3 catalog (Vasiliev and Baumgardt, 2021) and new average distances (Baumgardt and Vasiliev, 2021) in the axisymmetric three-component potential with spherical bulge, disk component, and spherical dark Navarro-Frank-White halo (Bajkova and Bobylev, 2016). The new orbital parameters are compared with the orbital parameters constructed by us earlier (Bajkova and Bobylev, 2021) in the same gravitational potential using proper motions obtained from the Gaia DR2 catalog (Vasiliev, 2019) and with the distances from the Harris catalog (2010).
