Orbits of 152 Globular Clusters of the Milky Way Galaxy Constructed from the Gaia DR2 data
read the original abstract
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).

Neighbors, Not Kin: Kinematic evidence for tidal tails from NGC 7492 along the Sagittarius stream
GIRAFFE radial velocities and metallicities confirm NGC 7492 tidal tails extending ≥1.8 deg, kinematically and chemically distinct from the overlapping Sagittarius stream.
