Only a handful of giant planets do have constraints on their emission at visible wavelengths. Therefore, little is known about the processes that make those objects bright or dark. Incident stellar flux, atmosphere composition and dynamics play a salient role in producing the planetary emission. The precise photometry obtained with the Kepler mission allows to probe the planetary emission at visible wavelengths for a large sample of giant planets exhibiting various orbital and physical properties.
We present a comparative study aiming at characterizing hot-Jupiters visible flux in the Kepler bandpass. Our results show that irradiated giant planets do have both reflective and dark atmospheres. The statistical significance of our sample allows to constrain the possible origins of this diversity and emphasizes how Kepler contributes to the growing field of comparative exoplanetology.
Kepler was selected as the 10th mission of the Discovery Program. Funding for this mission is provided by the NASA Science Mission Directorate.
