Outline of Final Research Achievements

Using a high contrast IR-imager, we have completed the Subaru Strategic Program, SEEDS and found or confirmed 4 planets and 3 brown dwarfs via direct imaging technique. We have also revealed fine-structurs within the 30 circumstellar disks, reported for the first time the gaps and arms of the solar-system scale. Furthermore, we have developed a precision IR spectrometer for exoplanet detection including wide-band laser frequency comb, echelle grating, ceramic optics, low-vibration cryostat, and others.
