Super-Earths: A New Class of Planetary Bodies
, 2011 Super-Earths, a class of planetary bodies with masses ranging from a few
Earth-masses to slightly smaller than Uranus, have recently found a special
place in the exoplanetary science.Armitage P. J., Christensen U. R., Clubb K., Dobrovolskis A. R., Fogg M.

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.

, 2018 Gravitational microlensing finds planets through their gravitational
influence on the light coming from a more distant background star. The presence
of the planet is then inferred from the tell-tale brightness variations of the
