Velocity dispersion evolution in Sco-Cen OB

We study how the stellar velocity dispersion within the Scorpius-Centaurus OB association (Sco-Cen) has evolved over approximately 20 million years, from its formation to the...本研究探讨了天蝎-半人马座OB星协（Scorpius-Centaurus OB association，简称Sco-Cen）内部的恒星速度弥散（stellar velocity dispersion）在约2000万年的时间尺度上，从其形成初期至……的演化历程。
