Temperature effects on exoplanetary atmospheric (bio)markers
Résumé
We have developed a photo-thermo-chemical model adapted to the study of the hot terrestrial atmospheres. Such a model is essential to interpret future observations and to predict the composition of hot extrasolar terrestrial planets. It is also important to understand the formation and the evolution of some of their key atmospheric species. We investigate here the effect of an increase of the temperature on the predicted abundances of some of these key species, such as ozone O3 and carbon dioxide CO2.
