Notes.
The parameters of KIC 5892969 are taken from Huber et al. (2014) and those of CoRoT stars are taken from the CorotSky Database (Charpinet et al. 2006).
Mean density (ρ), mass (M), and radius of a star with spherical symmetry (R; see Sect. 5).
Centrifugal to gravity force ratio (ϵ2), oblateness (O), polar and equatorial radii of the star (Rp and Re), and gravity-darkening effect (δTeff; see Sect. 2.2).
Convective efficiency and kinetic energy of the wave are both related to the convective layer of the star (see Sect. 2).
