Comparison of three identical models in terms of input parameters, but featuring different levels of correction to the luminosity profile. The zeroth-order model assumes Lr ∝ Mr and corresponds to the seismic structure uncovered by Giammichele et al. (2018, dotted lines in black). The model with the first-order correction (dashed curves in blue) shows profiles determined from the interpolation of kν in the grid of “generic” evolutionary models. The model with the second-order correction (plain curves in red) shows profiles corrected for the particular chemical stratification of the model considered.
