The Italian ARIEL meeting

Dr. Daniele Galuzzo presented yesterday at the Italian ARIEL meeting our new model for exoplanet atmospheres. Based on a 3D General Circulation Model, it is able to derive the dynamical properties of the atmosphere. Furthermore we combined the GCM with a radiative transfer code so that our model give as as output high resolution spectrum of the planet, both reflected and thermal spectrum. We applied our model to the interesting case of the nearest exoplanet to Earth: Proxima Centauri b. We also proposed a photometric method for direct detection in the IR of the atmospheric features using JWST or ELT class groundbased telescopes.
