Links with the orbital motion of HD 118203 b. Left panels: orbital path of HD 118203 b, which follows the anticlockwise direction. The circles represent the location of HD 118203 b every ≃1.5 h and are coloured in red, blue, or white, depending on whether the photometric flux increases, decreases, or remains stable during that time lapse, respectively. Centre panels: TESS PDCSAP photometry of HD 118203 folded in phase with the orbital period of HD 118203 b and binned with ≃5% phase bins. The cyan line corresponds to the filtered photometry through a median filter with a kernel size of 701 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: comparison between the derivative of the phase-folded PDCSAP photometric variations of HD 118203 and the angular velocity of HD 118203 b. The orange circles correspond to binned data of 7% the orbital phase. In all panels: the green and magenta squares represent the periapsis and apoapsis of the orbit, respectively, and the white and grey backgrounds represent the orbital regions in which a hypothetical stellar co-rotating active region would be visible and not visible from Earth, respectively.
