Draco II stars gi magnitude & radial velocities

We present the first spectroscopic analysis of the faint and compact stellar system Draco II (Dra II, M_V_=-2.9+/-0.8,r_h_=19^+8^-6_pc), recently discovered in the Panoramic...

我们首次对近期在Panoramic……中发现的暗弱致密恒星系统天龙座II（Dra II，V波段绝对星等$M_V=-2.9pm0.8$，半光半径$r_h=19_{-6}^{+8}$秒差距）开展光谱分析。
