Title: High Spatial Resolution Observations of CoRoT Exoplanetary Candidates

Abstract: With the launch of CoRoT, detection of transiting exoplanets will be pushed to lower and lower planetary masses. CoRoT-7b may be the first discovery of an 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 two nights of Keck II with NIRC2 NGSAO and three nights on WIYN with SPECKLE to obtain high spatial resolution observations of promising CoRoT transiting candidates. The targets will be observed prior to, during, and after transit to search for variations of background sources corresponding to the transit times. The near- infrared and visible bandpasses of the two instruments enable sensitivities to slightly different background stars making the two observing programs complementary for our scientific goals. The superior capabilities of the Keck and WIYN telescopes will uniquely contribute to the discovery of the smallest known transiting exoplanets.
