EXOPLANET IMAGING AT MID-IR WAVELENGTHS WITH JWST

摘要

Numerical simulations have been carried out to assess the opportunity to detect extrasolar planets with MIRI: the mid-IR instrument of JWST. As a result, we found that very young planets (50Myr) as well as old planets (5Gyr) can be imaged in the thermal-IR (5μm to 20μm) down to a few Jupiter masses if an appropriate high-contrast coronagraph is in used. Promising results of numerical simulations are presented. Characterization can also be tentatively performed with photometric data using specific narrow band filters.
