GD-1 and Kshir tidal streams metallicity and motion

To explore the metallicity and kinematic properties of stellar streams, we selected the members of the GD-1 stream and Kshir stream, and conducted out a detailed analysis of the...为探究恒星流（stellar streams）的金属丰度与运动学特性，我们选取了GD-1星流（GD-1 stream）与Kshir星流（Kshir stream）的成员天体，并对其开展了细致的分析……
