Internal structure of the five points (indicated by the numbers in each panel) marked in Figure 5. The left panel for each point shows N and S _ℓ for harmonic degrees ℓ = 1 and 2. The dashed line indicates the frequency of maximum power ν _max of the stochastically excited solar-like modes. The vertical dotted lines mark the radius of the model. Right panels show temperature, hydrogen and helium mass fractions, mass, luminosity, and the nuclear energy generation rate. Gray areas mark convective regions according to the Schwarzschild criterion.
