Astrometric Microlensing Events Predicted from Gaia DR2

From the Gaia DR2 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (µ_tot >150mas/yr) passing a background source in the next...本研究基于盖亚第二数据发布版（Gaia DR2）星表，对总自行µ_tot >150mas/yr的高自行前景恒星在未来掠过背景源时所引发的天体测量微引力透镜事件进行预测。
