Scientific paper

METIS (the Mid-infrared E-ELT Imager and Spectrograph) is a 3- to 14-micron multimode instrument for the 42-meter European Extremely Large Telescope (E-ELT). The instrument modes currently under study include direct and coronagraphic imaging, long-slit spectroscopy, integral field spectroscopy and polarimetry. METIS will be interfaced with the E-ELT adaptive optics system, and incorporate its own on-axis natural guide star wavefront sensor, and thus achieve Strehl ratios above 90% in N band. In this paper we will describe two of the main science goals of this instrument: direct imaging of exoplanets as well as the characterization of protoplanetary disks. Because of the superior angular resolution and high contrast, METIS at the E-ELT will be able to image exoplanets at considerably closer orbits than its cooperative competitor the Mid-infrared Instrument (MIRI) on the James Webb Space Telescope (JWST).
