AI-generated Key Points
- The SPICA Coronagraph Instrument (SCI) is used for direct detection and spectral characterization of outer exoplanets.
- It provides high-contrast imaging and moderate resolution spectroscopy at the wavelength range from 3.5 to 27 \mu m.
- SCI will search for gas giant planets down to one Jupiter mass around nearby young (1 Gyr) stars and two Jupiter masses around nearby old (5 Gyr) stars.
- SCI allows for characterizing those planets of less than 1 Gyr by spectroscopic observations to reveal the nature of planetary formation and evolution.
- SCI enables us to directly image icy giant planets like Uranus and Neptune as well as gas giant planets around nearby early-type stars.
- This capability makes it possible to study the atmospheres of these planets in detail, including their composition, temperature structure, and dynamics.
- In comparison with other instruments such as the JWST coronagraphs, SCI has unique advantages in terms of its sensitivity and wavelength coverage.
- A new approach to answering questions concerning the formation and evolution of planetary systems through planet detection with SCI has been proposed which represents a significant step forward in our ability to study exoplanets directly.
Abstract: The SPICA coronagraph instrument (SCI) provides high-contrast imaging and moderate resolution (R < 200) spectroscopy at the wavelength range from 3.5 to 27 \mu m. Based on the planet evolutional model calculated by Burrows et al. (2003), SCI will search for gas giant planets down to one Jupiter mass around nearby young (1 Gyr) stars and two Jupiter masses around nearby old (5 Gyr) stars. SCI also allows to characterizing those planets of less than 1 Gyr by spectroscopic observations to reveal the nature of planetary formation and evolution. Focusing on the high sensitivity and high contrast at wavelengths longer than 10 \mu m, we show that SCI also allows us to directly image icy giant planets like Uranus and Neptune as well as gas giant planets around nearby early-type stars. In this paper, we compare the capabilities of SCI and the JWST coronagraphs and also discuss a new approach to answering questions concerning the formation and evolution of planetary systems through planet detection with SCI.
