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.
