Spitzer | Warm Spitzer Photometry of the Transiting Exoplanets CoRoT-1 and CoRoT-2 at Secondary Eclipse2011, Deming, Drake, Knutson, Heather et al. |
The spectrum of CoRoT-2 is unusual because the 8 μm contrast is anomalously low. |
Dayside Temperature (occultation): 999999 K |
Spitzer | The thermal emission of the young and massive planet CoRoT-2b at 4.5 and 8 μm2010, Gillon, M., Lanotte, A. A. et al. |
Poor heat distribution on the night side of the planet and agree better with an atmosphere free of temperature inversion |
