Stellar pulsation signal seen from variation in the stellar v sin i_*. The stellar CCF are cleaned from the local stellar and planetary atmosphere spectra, and fit with a stellar rotation profile. The pulsation period is P_puls = 7.54 ± 0.12 h, and is consistent between the two nights (in dark blue and green, respectively) that are separated by one year. The averaged v sin i_* is reported for each night with the horizontal dashed lines, and has an averaged value of v sin i_* = 112.60 ± 0.04 km s⁻¹.
