Hot Jupiter Model Atmospheres in the Spitzer Era

摘要

The Spitzer Space Telescope has allowed observers to detect thermal flux from the atmospheres of hot Jupiters. We present model atmospheres of several of these planets and compare our computed infrared spectra to recent space-based and ground-based infrared observations. We also explore spectra as a function of orbital phase for a three-dimensional dynamical atmosphere model of planet HD 209458 b. The temperature structure and blackbody-like day-side spectra of the dynamical model is quite different than other models. We also discuss why hot Jupiters are predicted to be dark at visible wavelengths.
