2D graph of the density of the converged model of a circumstellar viscous outflowing disk of a (near) critically rotating star in the very inner region up to 5 stellar radii, corresponding to the disk mass-loss rate Ṁ = 10⁻⁶ M_⊙ yr⁻¹, with the constant viscosity parameter α = α₀ = 0.1. The parameters of the star correspond to average parameters of Pop III stars (see Table 1) or sgB[e] stars (e.g., Kraus et al. 2007). The sonic point is in this case at a distance of approximately 2 × 10⁴ R_eq. The density profile shows in this case irregular bumps in the very inner disk region. The contours mark the density levels (from lower to higher) 10⁻⁹, 10⁻⁸, 10⁻⁷, 10⁻⁶, 2.5 × 10⁻⁶, 5 × 10⁻⁶ [kg m ⁻³], and so on, with a constant increment of 2.5 × 10⁻⁶ kg m⁻³.
