Exploring the Climate of Exoplanets with OASIS

In the last two decades, the astrophysical community discovered a multitude of planets orbiting other stars. The variety of planetary environments that these exoplanets may harbour is still unknown. Most importantly it propels the fundamental scientific and philosophical quest of searching for the first detection of life beyond our own planet. As more observational data become available, models of exoplanetary atmospheres are essential, at a first level to interpret the data and more importantly to reproduce and explain the physical and chemical processes that generate the climate of planets.

My poster presents the new planet simulator, OASIS, that I have developed from scratch to study planet's habitability and search for life in exoplanets. Our new planetary virtual lab includes a new state-of-the-art 3D atmospheric model (THOR) coupled self-consistently with other modules that represent the main physical and chemical processes that shape planetary climates and their evolution. We have recently submitted a manuscript presenting our first results using OASIS. Using our new platform, we successfully performed challenging simulations of Venus-like environments and compared the model's results to Venus observations. We will present our new results and describe the main advantages of using OASIS compared with other models. The new results show that OASIS is a robust and efficient tool to simulate a large diversity of planet's environments.
