Caption: Figure 14.
Ratio of the kinetic energy in the gravity-wave propagation zone to the total kinetic energy, Ek,g/Ek, for dipole axisymmetric modes as a function of frequency. The model shown reproduces the frequency 4.4416 day−1 as the first radial overtone. Red dots mark the frequencies of radial modes, and vertical lines indicate the observed frequencies derived from the TESS data.
