In this research, we have aimed to search and characterize Earth-like or super-Earth planets around nearby M dwarfs (stars with lower temperature than the Sun).To realize such studies, we first established a methodology to achieve high precision observations, and then we conducted a survey for new exoplanets using 188cm telescope at Okayama Astrophysical Observatory. The survey is still ongoing, but we are preparing a paper for our initial results. In addition, we observed two known such exoplanets, named GJ1214b and GJ3470b, and revealed atmospheric nature of those planets.
