Title: Ultrahot Jupiters and the Magnetic Circulation Regime
Abstract With orbital periods of only a few days, ultrahot Jupiters (Teq>2200) are the hottest class of exoplanets known. Due to their proximity to their host star, these planets are expected to have tidally synchronous orbits, resulting in a permanent dayside and nightside and complex temperature structures around the planet. Using 3D numerical atmospheric modeling, I simulate these atmospheres with our state-of-the-art kinematic MHD approach. When applied, the planetary circulation changes to a magnetic circulation regime. In this talk I describe this regime as well as observational signatures present in high-resolution spectroscopy.
