Artist’s rendition illustrating star-planet interaction-induced radio emission. This illustration summarizes the physical processes driving radio emission, from the star’s activity to the direct energy flux generated by Alfvén waves (green color) electron acceleration at relativistic velocities (red color circles), resulting in cyclotron radio emission (red cone). The image also highlights the use of a 3D MHD stellar wind simulation, specifically the Alfvén Wave Solar Model (AWSoM) and WindPredict_AW. These wind models are coupled with the ExPRES code to simulate and predict the SPI-induced radio emission.
