KEOPS: towards exo-Earths from Dome C of Antarctica
International audience This paper describes a coronagraphic nulling interferometer called KEOPS (Kiloparsec Explorer for Optical Planet Search) to be placed on the Dome C plateau of Antarctica. KEOPS is an interferometric array of 39 1m 2m telescopes spread over kilometric baselines and operated in...
