Planetary Magnetic Response to Young Star Stellar Wind Environment
Abstract
Young stars are known to exhibit strong magnetic activity in the form of both steady and eruptive outflow. This, combined with the majority of known Earth-like planets orbiting their stars closer than Mercury orbits the Sun, results in an extreme stellar wind environment at the planet. We employ a 3D coupled MHD model to simulate the planetary response to this environment with an emphasis on the exchange of plasma between the planetary magnetosphere, ionosphere and stellar wind. We will present the results of two cases: the case of extreme, steady stellar wind and the case of successive Sun-like Coronal Mass Ejection (CME) impacts over short timescales. These results demonstrate how exoplanetary environments differ from Earth's and provide insight into how early stage star-planet interactions may impact future evolution of the planetary environment.
