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.
