GLS periodogram of the ESPRESSO RVs and the spectroscopic activity indicators. The vertical grey lines indicate the transit-like signals with periods of 13.176 and 3.307 days. The vertical red line shows the frequency corresponding to the possible rotational period of the star at ~29 days. The dashed, dash-dotted, and dotted horizontal lines show the 10%, 1%, and 0.1% FAP levels, respectively.
