Expected flux density for auroral radio emission arising from star-planet interaction in the system HD 260655-HD 260655 b, as a function of orbital distance. The interaction is expected to be in the sub-Alfvénic regime (i.e., Alſven Mach number M_A = (υ_rel/υ_Alfv ≤ 1;> top panel) at the location of the planet (vertical dashed line). The planet in the bottom panel is drawn at 0.1 mJy in the y-axis. The radio emission expected from the interaction between the planet and its host star holds promises for detection, and we encourage observations to test star-planet interaction scenarios.
