Young groups and clusters from GES and Gaia EDR3

We present the first large-scale 3D kinematic study of ~2700 spectroscopically confirmed young stars (<20Myr) in 18 star clusters and OB associations (hereafter groups) from...本研究首次针对来自……的18个星团与OB星协（OB associations，以下简称群）中的约2700颗经光谱证认、年龄小于20百万年的年轻恒星，开展了大规模三维运动学研究。
