Tidally excited pulsations of V346 Cen. Top: observed light curve of V346 Cen for sectors 37 and 38, phase-folded with the binary orbital period. The eclipses are indicated by the grey bands. Middle: pulsation light curve of V346 Cen for sectors 37 and 38, phase-folded with the binary orbital period. Data points taken during the eclipses again lie within the grey bands. Bottom: Lomb–Scargle periodogram, calculated for the out-of-eclipse data points of the pulsation light curve for sectors 37 and 38. The vertical dashed lines indicate harmonics of the orbital frequency.
