The Astronomical JournalThe gravitational microlensing technique is most sensitive to planets in a Jupiter-like orbit and has detected more than 200 planets. However, only a few wide-orbit ( s > 2) microlensing planets have been discovered, where s is the planet-to-host ...Ruocheng Zhai, Radosław Poleski, Weicheng Zang, Youn Kil Jung, Andrzej Udalski, Renkun Kuang, Leading Authors, Michael D.
