Abstract

The future winter operation of the new permanent station on the Antarctic plateau at Dome Concordia is a strong motivation to investigate the potential of the site for astronomical observations.  Recent site seeing testing campaigns conducted by our team from University of Nice show that Dome C represents the best site on Earth for astronomical high angular resolution (HAR) observations at optical and IR wavelengths.  The dramatic gain over relevant HAR parameters r0, L0, θ0 and �?�0, added to very low temperatures during the polar winter nights (-70 °C), the dry atmosphere and the possibility of continuous observations during several nights make Dome C the ideal site for deploying a kilometric optical interferometer before the 2015 horizon. Here we describe the concept of Kiloparsec Explorer for Optical Planet Search (KEOPS) that is studied by our group at LUAN. KEOPS is an interferometric array of 36 off-axis telescopes, each 1.5m in diameter.  Its kilometric baselines open sub-mas snap-shot imaging possibilities to detect and characterize extra-solar planetary systems specially exo-Earths out to 300 parsecs from the visible to the thermal IR.
