Kinematics of horizontal-branch stars from SDDSS-DR7

On the basis of a recently derived color-metallicity relation and stellar parameters from the Sloan Digital Sky Survey Data Release 7 spectroscopic survey, a large sample of red...本研究基于新近推导得到的颜色-金属丰度关系（color-metallicity relation），以及取自斯隆数字巡天（Sloan Digital Sky Survey）第七次数据发布（Data Release 7）光谱巡天的恒星参数，构建了一个大样本的红色……样本。
