Improved kinematic parallaxes for Sco-Cen members

We present an analysis of the ages and star formation history of the F-type stars in the Upper Scorpius (US), Upper Centaurus-Lupus (UCL), and Lower Centaurus-Crux (LCC)...本研究针对天蝎-半人马座上星协（Upper Scorpius，US）、半人马-豺狼座上星协（Upper Centaurus-Lupus，UCL）以及半人马-南十字座下星协（Lower Centaurus-Crux，LCC）内的F型恒星的年龄与恒星形成历史展开分析
