摘要：

Numerical simulations have been carried out to assess the opportunity to detect extrasolax planets with MIRI: the mid-IR instrument of NGST. Several coronagraphs and telescope designs have been investigated. As a result, we found that very young planets (50Myr) as well as old planets (5Gyr) can be imaged in the thermal-IR (5mum to 20mum) down to a few Jupiter masses if an appropriate high-contrast coronagraph is in used. Promising results of numerical simulations are presented.
