Title: Close visual companions to transiting exoplanet host stars

Abstract: We propose to conduct a high resolution imaging survey of transiting planet host stars to identify spatially close companions. Recent results have demonstrated that unresolved stellar companions (physical or visual) to transiting planet host stars can dramatically affect the calculated planetary masses and radii, potentially leading to biases in our understanding of their composition and formation. Furthermore, this survey will provide a more complete assessment of the frequency of planets in binary star systems, the results of which are important for determining the total number of planets in the galaxy.
