Theoretical Spectra and Light Curves of Close-in Extrasolar Giant Planets and Comparison with Data

Understand

We present theoretical atmosphere, spectral, and light-curve models for extrasolar giant planets (EGPs) undergoing strong irradiation for which {\it Spitzer} planet/star contrast ratios or light curves have been published (circa June 2007).

• These include HD 209458b, HD 189733b, TrES-1, HD 149026b, HD 179949b, and $\upsilon$ And b.
• By comparing models with data, we find that a number of EGP atmospheres experience thermal inversions and have stratospheres.
• This is particularly true for HD 209458b, HD 149026b, and $\upsilon$ And b.
