Habitability of exoplanets is commonly determined by the planetary surface temperature, which allows liquid water to exist. However, extreme space weather and interplanetary conditions that include the stellar wind and Coronal Mass Ejections (CMEs), can impact the ability of close-in planets to sustain their atmospheres, unless they are shielded by an intrinsic magnetic field. Here we present a series of numerical MHD simulations of a stellar corona harboring a close-in planet. We study the planetary impact on the stellar corona, and characterize the ability of the planetary magnetic field to shield the planetary atmosphere from erosion by both the ambient stellar wind and CMEs. We also estimate the energy transferred to the planet via the interaction with a CME and predict the global structure of the aurora generated by the space weather event. The simulations we present are highly realistic and are not based on idealized scenarios.
