| Research Abstract |
Metal-poor stars and globular clusters are main consituents of the old Milky Way components, the stellar halo. Detailed chemical abundances and kinematics of these objects provide us important insights into the early chemodynamical evolution of our Galaxy. In this study, we studied 1) chemical abundances of metal-poor stars in the solar neiborhood and its correlation with the structure of the thick disk, the inner and outer stellar halos and 2) radial velocity and metallicity measurements of a tidally disrupting Galactic globular cluster Palomar 5.
