Sinusoidal signals within the TESS photometry of TOI-5005. Left panels: Photometric time series without the TOI-5005.01 transits. The orange circles correspond to 1.3-day binned data. Centre panels: Generalized Lomb-Scargle Periodograms of the time series. The vertical magenta dashed lines indicate the orbital period of TOI-5005.01. The green circles and boxes indicate the maximum power frequencies. Right panels: Photometric time series folded to the orbital period of TOI-5005.01. The phase is referred to the time of inferior conjunction. The orange circles correspond to data binned over phase windows of 0.1 in width.
