10 Sep 2014 | | Abstract: | METIS will be among the first generation of scientific instruments on the
E-ELT. Focusing on highest angular resolution and high spectral resolution,
METIS will provide diffraction limited imaging and coronagraphy from 3-14um
over an 20"x20" field of view, as well as integral field spectroscopy at R ~
100,000 from 2.9-5.3um. In addition, METIS provides medium-resolution (R ~
5000) long slit spectroscopy, and polarimetric measurements at N band. While
the baseline concept has already been discussed, this paper focuses on the
significant developments over the past two years in several areas: The science
case has been updated to account for recent progress in the main science areas
circum-stellar disks and the formation of planets, exoplanet detection and
characterization, Solar system formation, massive stars and clusters, and star
formation in external galaxies. We discuss the developments in the adaptive
optics (AO) concept for METIS, the telescope interface, and the instrument
modelling. Last but not least, we provide an overview of our technology
development programs, which ranges from coronagraphic masks, immersed gratings,
and cryogenic beam chopper to novel approaches to mirror polishing, background
calibration and cryo-cooling. These developments have further enhanced the
design and technology readiness of METIS to reliably serve as an early
discovery machine on the E-ELT. | | Source: | arXiv, 1409.3087 | | Services: | Forum | Review | PDF | Favorites | |
