Abstract
AbstractWe have started a conceptual design study for both a near-infrared (NIR) wide-field camera and a mid-infrared (MIR) camera-spectrograph for a 2m-class telescope at Dome C, Antarctica. The main scientific drivers are the characterization of young embedded objects, the evolution of crystalline silicates in circumstellar disks and the observation of exoplanet secondary transits. Both instrument would exploit the unique features of Dome C: superb seeing, low temperature, improved infrared transmission, reduced sky background and increased atmospheric stability. Two preliminary concepts are presented here. The NIR instrument would cover the wavelength range 0.9–5.5μm and would be optimized for the K, L and M bands. The MIR instrument would observe in the range 7–40μm and would be optimized for the Q window, including the extended portion (25–40μm) only observable from Antarctica.KeywordsUnique FeatureWavelength RangeConceptual DesignAtmospheric StabilityScience ProceedingThese keywords were added by machine and not by the authors.
