"The Antarctic Planet Interferometer"

Abstract: The Antarctic Planet Interferometer (API) is a concept designed to detect and characterize extrasolar planets by exploiting the unique potential of the best accessible site on Earth for thermal infrared interferometry. The best sites on the Antarctic plateau are excellent for infrared interferometry because the atmosphere at these locations is characterized by slow, low-altitude turbulence, low water vapor content, and low temperature. The three high-precision interferometric techniques under development for extrasolar planet detection and characterization (astrometry, differential phase and, nulling) all benefit substantially from these unique properties of the Antarctic plateau atmosphere. At these locations (such as the site being developed at Dome C), an interferometer with two-meter diameter class apertures has the potential to deliver space-like performance.
