Title: A Near-infrared Exoplanet Transit and Eclipse Survey

Abstract: We propose additional observations in our near-IR (JHK-band) exoplanet transit and eclipse survey. Our survey has three principal science goals: 1) measure radii for transiting planets using high S/N transit data in the J-band, 2) measure thermal emission of the hottest planets in JHK bands to infer the nature of the exoplanetary atmospheric structure and dynamics, 3) confirm or reject the existence of transit timing variations as they are announced by other investigations, and provide precision ephemerides to benefit space-borne observations. During this observation period we will measure accurate planetary radii for several giant planets lacking high-precision follow-up photometry, add additional transit times to our timing data base, and derive needed updates to the transit ephemerides for several planets being observed by Warm Spitzer. We will observe J- and K-band secondary eclipses of the hottest known exoplanet, WASP-33b. Our eclipse measurements will test the hypothesis that the most strongly irradiated planets absorb stellar irradiation efficiently, but circulate heat poorly.
