Abstract:
High-contrast imaging can find and characterize gas giant planets
around nearby young stars and the closest M stars, complementing
radial velocity and astrometric searches by exploring orbital
separations inaccessible to indirect methods. Ground-based
coronagraphs are already probing within 25AU of nearby young stars to
find objects as small as 3M{Jup}. This paper contrasts near-term and
future ground-based capabilities with high-contrast imaging modes of
the James Webb Space Telescope (JWST). Monte Carlo modeling reveals
that JWST can detect planets with masses as small as 0.2M{Jup}
across a broad range of orbital separations. We present new
calculations for planet brightness as a function of mass and age for
specific JWST filters and extending to 0.1M{Jup}.
