Research Abstract

We, the MOA collaboration, conducted an exoplanet survey by using gravitational microlensing for three years and found 5,6,9 planets in 2011,12,13, respectively. One of these events, MOA-2011-BLG-262Lb may have a mass of less than the earth to be confirmed near future. The another planet, MOA-2011-BLG-293Lb was the first exoplanet in the habitable zone found by microlensing. we estimated the planetary abundance outside of the snow line and found the abundance is several times higher than that inside the snow line. We also found dozen free floating planet candidates.
