We have created a new model to study the atmosphere of exoplanets. Derivated from a car engine combustion model, it is particularly adapted to the high temperature chemistry occuring in the atmosphere 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. Preliminary results of a 1D thermo-photochemical model for HD 209458b are presented.
