Stellar activity diagnostics calculated by serval. From top to bottom: Ca II IRT index calculated from the middle line of the triplet at ±15 km s⁻¹; the chromatic RV index, which represents the dependence of RV on wavelength and is clearly affected by the transiting planet; Hα activity index calculated for bin a of ±40 km s⁻¹ centred on the line core; and the differential Line Width again impacted by line deformation caused by the transiting planet. Overall the star presents no significant sign of variability due to activity.
