Cloudy with a hint of magnetic fields — •Ludmila Carone — St Andrews University, St Andrews, UK — Max Planck Institute for Astronomy, Heidelberg, D

In this review talk, I will present the state of the art of numerical models of exoplanet atmospheres. I will show why it is important to consider that exoplanets are three dimensional objects that can change their local observed atmosperic gas phase composition (C/O ratio) via cloud formation and disequilibrium chemistry. Since C/O ratios are used as proxies for exoplanet formation it is important that 3D processes are incorporated in the interpretation of upcoming detailed observations with next generation space telescopes: i.e. the James Webb Space Telescope, ARIEL and also PLATO. Last but not least, tackling magnetic fields interaction and how they impact observable properties in exoplanet atmospheres is an ongoing numerical challenge.
