Example for modulations of some non-radial pulsations during the exoplanet transit phases in a system with aligned orbit (i = 90°, λ = 0°). The four panels on the left show the residuals in the signals after the subtraction of mode (0,0). The panels on the right show the variations in the amplitudes (top) and phases (bottom) of all visible non-radial modes. Note: the small vertical scale of the phase modulation diagram implies that such a change will be barely noticeable.
