Title: High Spatial Resolution Observations of CoRoT Exo-planetary Candidates

Abstract: With the launch of CoRoT, detection of transiting exoplanets is being pushed to lower and lower planetary masses. CoRoT-7b is the first discovery of an transiting earth-sized exoplanet. As with ground-based surveys, CoRoT candidates need to be screened for background eclipsing binary stars which, when photometrically blended with the primary target, can mimic exoplanetary transits. High spatial resolution imaging obtained in and out of transit can be used to discriminate efficiently between foreground and background eclipsing sources and to provide an assessment of the transit candidate stars independent of radial velocity observations. We are requesting three nights on WIYN with SPECKLE to obtain high spatial resolution observations of promising CoRoT transiting candidates. The targets will be observed in and out of transit to search for variations of background sources corresponding to the transit times. The optical bandpass of the instrument mimics that of the spacecraft enabling sensitivities to stars to which CoRoT itself is sensitive. The superior capabilities of the WIYN telescope will uniquely contribute to the discovery of the smallest known transiting exoplanets.
