Upper panel: as in Fig. 6, up to the intermediate distance of 50 stellar equatorial radii. The near-equatorial strip of enhanced temperature exceeds in this case the distance 50 R_eq. The contours mark the temperature levels 1000 K, 2000 K, 5000 K and 10 000 K. Lower panel: color map of the temperature distribution in the very inner part (up to 5 stellar equatorial radii) of the dense circumstellar outflowing disk of a (near) critically rotating star with the same parametersas in Fig. 4, however, the parameterized disk mass-loss rate is in this case Ṁ = 10⁻⁷ M_⊙ yr⁻¹. The region of increased temperature generated by the viscous heating near the disk midplaneis in this case significantly reduced and extends up to only approximatively 4 R_eq. The contours mark the temperature levels 5000 K, 10 000 K, 20 000 K, 30 000 K and 40 000 K.
