TESS light curves and frequency spectra of 14 Peg: (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. (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) Same as in panel c but after removing instrumental trend.
