Predicted radio power from star-planet interaction for Tau Boo, HD 179949, and HD 189733 (black circles), with error bars representing the range of assumed planetary magnetic field strengths – from no field (R_M = R_p) to B_p = 40 G. Colored bars indicate the minimum detectable radio power for SKA1-Low (purple), NenuFAR (gray), and LOFAR (green) for each system. We show both conservative (darker shade) and optimistic (fainted shade) values of the telescopes based on the upper sensitivity limit. Dashed ticks mark the detection thresholds, they correspond to the bottom of each colored box. The values below that are undetectable by the respective instrument.
