| Research Abstract |
We carried out a Doppler planet search program targeting intermediate-mass G-type giant stars in order to uncover properties of planets around intermediate-mass stars. From the program we discovered some new planets and brown dwarfs around them, which give us insight into formation and evolution of planets. In addition, we investigated detectability of short-period planets around intermediate-mass A-type dwarfs based on photometric transit observations by using the 30cm telescope installed at Tokyo Institute of Technology. We showed that we can achieve a differential photometric precision of less than 0.2% for such stars.
