Kinematic structure of the Galactic Center S cluster

We present a detailed analysis of the kinematics of 112 stars that mostly comprise the high-velocity S cluster and orbit the supermassive black hole Sgr A* at the center of the...本研究针对112颗恒星的运动学特性展开详细分析，这些恒星绝大多数隶属于高速S星团，并围绕位于……中心的超大质量黑洞人马座A*（Sgr A*）运行。
