Scientific paper

We discuss the results of a ground-based attempt at detecting thermal emission from exoplanets. We have observed the secondary eclipses of two of the hottest hot Jupiters using WIRCam on the Canada-France-Hawaii Telescope. These recently discovered exoplanets are expected to have sufficiently high temperatures and favourable planet-to-star radius ratios for near-infrared detection from the ground. K-band observations of their secondary eclipses will fill in the wavelength region that is most discrepant in theoretical models of the planets' thermal emission. Successful detections will also allow us to constrain the day-to-night-side heat redistribution for these exotic exoplanets, understand their energy budgets, and address the question of whether the hottest class of hot Jupiters is truly uniform.
