Resumen en inglés

We have developed a new model to study the atmospheres of exoplanets, adapted to the high temperature and conditions of the atmospheres of hot Jupiters. Such a model appears essential to interpret recent and future observations, predict the composition and understand the formation and evolution of these planetary bodies. Results of a 1D thermo-photochemical model for HD 209458b are presented. An important problem of photochemical model is the lack of high temperature photochemical data. In order to improve this situation, we have begun a campaign of measurement of VUV absorption cross section at high temperature for H2O, CO2, CH4 and CO. We will present the influence of these new experimental data on the thermo-photochemical model.< Leer menos
