Comparison of two period spacings of mixed dipole modes within the observable region of the spectrum. In particular, we show a model with a density jump located at the boundary between the convective and radiative core (blue solid line), and a model with a density jump located within the radiative core (orange solid line). The dashed lines denote the asymptotic period spacings for the model with a density jump (in black), and for the other model (in red). Furthermore, the grey lines correspond to the radial modes associated with the model with a density jump in the radiative core. Notably, we observe clear differences in their period spacings, even in areas where dipole modes are detectable.
