Periodograms with solid vertical lines that indicate the period of the planet candidate at 5 days in green and the star-related periodicities at about 8, 16, and 32 days in orange, red, and magenta, respectively. The 10, 1, and 0.1% FAP levels are marked as horizontal dashed, dash-dotted, and dotted gray lines, respectively. The peaks near one day correspond to aliases of the stellar rotation signal, introduced by the daily sampling of ground-based observations. Top panel: RV data periodogram. The red dot shows the strongest peak signal that is aligned with the orbital period of the planet. Bottom panel: residual periodogram after subtracting the planet and stellar activity signals from the RV data.
