3D Modelling of Magnetized Star-planet Interactions: Cometary-type Tails and In-spiraling Flows
Abstract
Close-in exoplanets interact with their host stars not only gravitationally but also through magnetized plasma outflows. Here, we identify the different types of such interactions based on the physical parameters that characterize the system. We perform 3D magneto-hydrodynamic (MHD ) numerical simulations to model the evolution of a variety of possible star-planet configurations, incorporating realistic stellar and planetary outflows. We explore a wide range of parameters and analyze the flow structures and magnetic topologies that develop.
