| Research Abstract |
Follow up observations of microlensing events were executed by world-wide observation network to find extrasolar planets. New planets (MOA-2007-BLG-192Lb, MOA-2008-BLG-310Lb、MOA-2009-BLG-319Lb) have been discovered. From the analysis of the distribution of planets, it is concluded that cold neptunes are common. As a by-product of microlensing observation, planet search with Transit Timing Variation method was done using B&C telescope. Then, a limit on the existence of second planets was imposed for WASP-5.
