Quest for Extrasolar Planets by Optical and Infrared Doppler Technique Bun’ei SATO Global Edge Institute, Tokyo Institute of Technology, 2ῌ12ῌ1 Ookayama, Meguro-ku, Tokyo 152ῌ8550 Abstract : To detect tiny wobble of stars in radial velocities due to gravitational pull of planets is a powerful technique to find extrasolar planets. We have made outstanding discoveries in planet searches around giant stars and in searches for hot-Jupiters with this technique by using high dispersion spectrographs at Okayama Astrophysical Observatory and Subaru Telescope so far. We are now trying to develop a new infrared high-dispersion spectrograph aiming to search for habitable rocky planets around low-mass stars. We here introduce our latest results obtained by the optical Doppler technique, and discuss future prospects for planet searches by the infrared Doppler technique.. ¹º»c. 2009 ¼ 2 ».
