I present the status and results from an ongoing project that uses 800 hours of the Spitzer Space Telescope to gather near-infrared photometric measurements of transiting extrasolar planet candidates detected by the Kepler Mission. The main purposes of this project is to validate planetary candidates, and to characterize confirmed planets.
By comparing the light curves spanning times of primary transit for candidates observed with Kepler and Spitzer, we can exclude significant sources of astrophysical false positives resulting from blends (e.g. background eclipsing binaries) that mimic an exoplanetary signature in the Kepler bandpass. I show how our infrared observations can help to validate the planetary nature of several candidates with small radii, which could be rocky in composition.
By combining occultation measurements of the reflected starlight in the optical with estimates of the thermal emission in the near-infrared, we are able to constrain the energy budget of a handful of hot-Jupiters and compare such constraints to those for other giant planets.
