Chemodynamical evolution of the Milky Way Galaxy as probed by chemical abundances of globular clusters

贫金属星和球状星团是古老的银河系组成部分--恒星晕的主要组成部分。这些天体的详细化学丰度和运动学为我们提供了对银河系早期化学动力学演化的重要见解。在这项研究中，我们研究了1)太阳附近贫金属星的化学丰度及其与厚盘结构、内晕和外晕的关系，以及2)潮汐分裂的银河系球状星团Palomar 5的径向速度和金属丰度测量。

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.
