Planetary Group Seminar: Beware of the abyss! - How the planetary interior shapes atmosphere composition and air mass flow in exoplanets (L. Carone)
I will present ongoing work, where I show that it is important to consider the importance of the lower boundary in both, rocky, and gas dominated extrasolar planets. For the rocky planets, I will highlight how surface friction alone can elicit different wind flow for tidally Exo-Earths around cool M dwarfs. These different climate states lead to very different shapes of the ozone layer on such planets. Also, the planetary atmosphere composition of the habitable TRAPPIST-1 planets is strongly shaped by processes in the rocky interior during the magma ocean outgassing phase. For the second, I will present novel results for the very dense and fast rotating hot Jupiters WASP-43b and WASP-18b, where the first will be a target for the early release science for the James Webb Space Telescope. Also, there, we find that wind flow interacts with the deep interior and can change the observed climate regime compared to the "nominal" hot Jupiters, which we predict leads to very cool night side to be observable in the mid-infrared.
