Title: Follow-up Observations of HATNet Transiting Planet Candidates with WIYN/WHIRC

Abstract: Transiting planets around bright stars are key objects for exploring the physical properties of planets outside the Solar System. The US- based HATNet survey is one of the leading efforts for discovering and characterizing these planets. Here we propose to use the WHIRC instrument on the WIYN~3.5,m to carry out follow-up observations of candidate transiting planet systems identified by HATNet. WHIRC will be used to obtain NIR time-series observations of 5 to 10 candidates to rule out eclipsing binary false positive scenarios. It will also be used to search for resolved stellar companions to $sim 100$ candidate planetary systems in order to rule out blended stellar eclipsing binary false positives, correct the masses and radii of confirmed planets for dilution from any companions that are found, and to constrain the fraction of hot Jupiter host stars with wide binary companions. The WIYN/WHIRC observations will provide sensitivity to high contrast companions ($Delta J sim 7$) down to approximately 1arcsec, whereas a companion proposal for WIYN/NESSI will provide sensitivity to even closer angular separations (approaching a few tenths of an arcsecond), but with lower contrast sensitivity ($Delta R sim $3--4).
