Coronagraphy with JWST in the thermal IR
LESIA, Observatoire de Meudon, 5 place J. Janssen, 92195
MIRI, the mid-IR instrument of JWST (James Webb Space Telescope), will include a coronagraphic device for which the ultimate goal is the detection and caracterization of extrasolar planets around nearby stars. In this paper, we describe the optical concept of MIRI and the instrumental choices that were made in phase A and B regarding the coronagraphic system. Finally, we will present numerical simulations that we carried out to evaluate the capability for detecting extrasolar giant gazeous planets.
