Kinematics and HR Diagrams of Southern Young Stars

We investigate the spatial distribution, the space velocities and age distribution of the pre-main sequence (PMS) stars belonging to Ophiuchus, Lupus and Chamaeleon star-forming...本研究针对隶属于蛇夫座（Ophiuchus）、豺狼座（Lupus）与蝘蜓座（Chamaeleon）恒星形成区的主序前星（pre-main sequence (PMS) stars），探究其空间分布、空间速度及年龄分布特征。
