MOA-2011-BLG-291
, 2018 We present the analysis of planetary microlensing event MOA-2011-BLG-291,
which has a mass ratio of $q=(3.8\pm0.7)\times10^{-4}$ and a source star that
is redder (or brighter) than the bulge main sequence. This event is located at

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.
