Kinematics of our galaxy

In the thesis study, the relationship between radial velocity and metal abundances of RR Lyrae star groups, one of the globular cluster stars of the Milky Way, was examined and their kinematic structures were investigated. 1897 RR Lyrae stars were selected from the General Catalog Of Variable Stars (GCVS) data set. The radial velocity data required for velocity measurements of selected stars were obtained from the archive of Gaia data early release 3 (Gaia Collaboration, 2020). The first face measurement of the 1897 RR Lyrae star was examined and its radial velocities were tried to be determined. Only 149 of these 1897 RR lyrae stars achieved radial velocity. RAVE data version 5 (Kunder+, 2017) was used for metal abundance analysis of stars. In addition, apart from this data, a star metal abundance analysis table was created by looking at the version of the LAMOST DR5 catalog (04/07/2019).
