Exoplanet Science with the SPICA Coronagraph Instrument

SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan
SPICA Coronagraph Instrument (SCI) is an instrument dedicated for direct detection and characterization of exoplanets and also for other science that needs a high-contrast imaging and spectroscopic capability in the near to mid-infrared wavelengths. We will present the major science cases for exoplanets from the instrument proposal of SCI. Thanks to the high-contrast imaging and spectroscopic capability, we will be able to tackle the various problems on the exoplanet science. SCI will give us the unique opportunity to observationally understand the formation process of Jovian planets, which is still poorly understood, by measuring temperatures of young Jovian planets. Spectroscopy of planet atmospheres will enable us to reveal the chemical compositions by measuring the abundances of various important molecules such as CO, CH4, NH3, H2O, H2 etc. We will also access to the structure of Jovian atmosphere, for example the existence of thermal inversion which is known for our Solar system planets. Furthermore, the direct detection of icy giants around early-type stars with SCI will open a new window to investigate these enigmatic planets.
