The different gas components in the atmosphere of exoplanets are exposed to different temperatures and pressure conditions that shape the spectral information captured by the telescopes. The development of robust theoretical tools to help unveiling the atmospheric composition of exoplanets will play an important role in the characterization of exoplanet atmospheres and in the interpretation […]

Summary In a recent publication, THOR helped unveiling the “dark-side” of WASP-43b ([view paper]). Running 3D simulations of cloudy atmospheres,  THOR produced multi-phase emission spectra that constrain a cloud deck to be confined to the nightside of the planet and have a finite cloud-top pressure. The produced spectra also suggests the possibility of enhanced carbon dioxide in the atmosphere […]

THOR is now open-source on this link. THOR is a flexible Global Circulation Model (GCM) that solves the three-dimensional non-hydrostatic Euler equations on an icosahedral grid, and was designed to run on Graphics Processing Units (GPUs). THOR was developed from ground-up with the propose of exploring a large diversity of planets and avoiding physical approximations brought from other research fields. This model has […]
