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, to compare with visible-wavelength and UV radii that may be larger due to atmospheric haze, 2) measure thermal emission of the hottest planets in JHK bands to infer the nature of the exoplanetary atmospheric structure, 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 a precise planetary radiius for HAT-P-31b, that currently lacks accurate follow-up photometry. We will also determine an infrared radius for the very inflated giant planet CoRoT-11 and other systems observed by Hubble and Kepler, and add additional transit times to our overall timing data base. We will observe the K-band eclipse of the hot planet HAT-P-23b, to complement observations by Warm Spitzer.
