Research Objectives

We conduct direct imaging of the gas planets which are close to fixed stars (1-40AU). By using Doppler spectroscopy, the transit method, and gravitational micro-lensing, we are able to detect extrasolar planets, and we aim especially to detect one solar mass star in the habitable zone. By using adaptive optics or coronagraph with the world’s top technique, we develop a high-contrast infrared spectrometer to conduct direct spectroscopy to the atmospheres of extrasolar planets or the dwarf galaxies, which are low-temperature planets, to understand the characteristics of extrasolar planets (called characterization). With a strong link between the theories of planet formation and the theories of planetary atmospheres by the other research planning teams A02 and B02, we can compare and analyze the observation results to understand the origin of a variety of extrasolar planets.
