Prediction of microlensing events with Gaia EDR3

Astrometric microlensing is a unique tool to measure stellar masses. It allows us to determine the mass of the lensing star with an accuracy of a few percent. In this paper, we...天体测量微引力透镜（astrometric microlensing）是测定恒星质量的独特手段。依托该方法，可实现对透镜恒星质量的高精度测定，测量精度可达百分之几。本文中，我们……
