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旧银河系组成部分--恒星晕的主要组成部分。详细的化学丰度和这些对象的运动学为我们提供了重要的见解，我们的银河系的早期化学动力学演化。在这项研究中，我们研究了1）太阳附近贫金属恒星的化学丰度及其与厚盘结构，内部和外部恒星晕的相关性和2）径向速度和金属丰度测量的潮汐破坏银河系球状星团Palomar 5。

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.
