Examples of classical pulsators observed in the light curves of binary systems. Left panel: OC binary (KIC 8330092) with an orbit of 0.32 days displaying γ Dor and maybe Rossby modes at ν ≲ 50 μHz and clear δ Sct oscillations above that. Middle panel: short-period detached system KIC 6852488 in which δ Sct oscillations are clearly visible at ν ≳ 120 μHz. The asymmetrical dispersion of points around the rebinned folded light curve is caused by the presence of spots that modulate the photometric variations as a function of time. Right panel: “long”-period detached EB KIC 2998124 displaying δ Sct oscillations at ν ≳ 170 μHz. Vertical dashed red lines indicate the orbital frequency . For left and middle plots, the gray curve is the modulus of the Fourier transform prior to removing harmonics of the orbital period.
