Temperature profiles ⟨ T ⟩ averaged over 900 inner orbits (red curves). Black plain lines show their corresponding theoretical profiles. Black dashed lines show their corresponding initial profiles. Top panel: σ_cold case. Bottom panel: σ_hot case. The subframes inserted in the upper right of each panel show the alpha profiles obtained in both cases (red lines). The dashed lines show the analytic profiles used to compute the theoretical temperature profile (see text), given by α = 6.3 × 10^-2 − 7.1 × 10^-3R/R₀ and α = 4.6 × 10^-2 − 5.7 × 10^-3R/R₀ respectively.
