Links between the orbital motion of TOI-5005 b and the TESS photometric variability of TOI-5005. Left panels: TESS photometry of TOI-5005 folded in phase with the orbital period of TOI-5005 b (Sect. 4.4, Table D.6) and binned with ≃5% phase bins. The orange line corresponds to the filtered photometry through a median filter with a kernel size of 1401 cadences. The blue, red, and white vertical lines indicate whether the photometry increases, decreases, or remains stable in time lapses of ≃1.5 h. Right panels: orbital path of TOI-5005 b, which follows the anticlockwise direction. The circles represent the location of TOI-5005 b every ≃1.5 h and are coloured similarly to the vertical lines in the left panels. In all panels the white and grey backgrounds represent the orbital regions in which a hypothetical co-rotating active region would be visible and not visible from Earth, respectively.
