论文摘要

我们使用平均GAIA DR2适当的运动和其他天文学数据从Vasiliev(2019)列表中获得了152个银河系的球状星系簇的轨道及其性能。对于轨道整合,我们已经根据Navarro-Frenk-white Dark Halo使用了银河电位的轴对称模型,并通过Bajkkova和Bobylev(2016)修改了Galactic对象的圆形速度(来自Bhattachacharjee et.al bhattacharjee等人的200 kpc)的圆形物体的圆形速度。 (2014)目录。基于对获得的轨道的分析,我们修改了Massari等人中呈现的球状簇子系统的组成。 al。 (2019)。

We present orbits and their properties for 152 globular clusters of the Milky Way galaxy obtained using average Gaia DR2 proper motions and other astrometric data from the list of Vasiliev (2019). For orbit integrating we have used the axisymmetric model of the Galactic potential based on the Navarro-Frenk-White dark halo, and modified by Bajkova and Bobylev (2016) using circular velocities of Galactic objects in wide region of Galactocentric distances (up to 200 kpc) from Bhattacharjee et.al. (2014) catalog. Based on the analysis of the obtained orbits, we have modified the composition of the subsystems of globular clusters presented in Massari et. al. (2019).
