BLS periodograms of TESS sectors 17, 18, and 24 (left panels) and the photometric data folded in phase (right panels), together with a roughly binned (orange line). Various harmonics are also identified with vertical thin red lines. Top panel: detection of the 2.52 d transiting planet (the strongest peak is marked with a vertical orange line). Middle panel: detection of a potential 15.41 d signal after masking the previous signal. The LC folded in phase does not show any evidence of a transit. Bottom panel: detection of the 18.08 d transiting-planet candidate (strongest peak) after masking the two previous signals. The LC data folded in phase appear to indicate a possible shallow transit.
