Upper Sco members rotational velocities

We present projected rotational velocities for 20 early-type (B8-A9) and 74 late-type (F2-M8) members of the ~5 Myr old Upper Scorpius OB Association derived from...本文报道了年龄约5百万年（Myr）的上天蝎座OB星协（Upper Scorius OB Association）的20颗早型（B8-A9型）与74颗晚型（F2-M8型）成员的投影自转速度（projected rotational velocity），相关数据源自……。
