TESS light curves and frequency spectra of p Vel A: (a) TESS light curve phased with the orbital period. Phase 0.5 corresponds to the epoch of the periastron passage. (b) Residuals from the fit of Kumar’s model. Red dots are median values in 0.01 phase bins. Grey stripe marks phases in the vicinity of the heartbeat. (c) Frequency spectrum of the light curve shown in panel b. Panels c and d: orbital harmonics are marked with red vertical dashed lines (except for TEOs, which are marked with blue) and labeled with n. (d) Frequency spectrum of the light curve shown in panel b with data at phases marked by the grey stripe removed. A small trend in the light curve was also removed.
