Thermodynamic structure of the starspots. Top: Average entropy in the umbral (solid), penumbral (dashed) and quiet star (dotted) region plotted against pressure in units of the pressure scale height ln(p/p₀) calculated from the pressure stratification in the quiet star region. Bottom: Temperature stratification for all the cases plotted against the gas pressure in logscale. The dashed vertical line represents the stellar surface. The bottom boundary is located towards the left side of the plot. The colors refer to the same stellar types as in Fig. 1.
