Radial dependence of the accretion rate onto the disk. The accretion rate is given in the units of the Eddington accretion rate, and R₈ is given in 10⁸ cm units. The solid line shows the initial distribution, the broken line shows the distribution of accretion rate on the disk after 40 days of evolution. Ṁ is taken from (14), with the following Ṁ₀: upper panel: Ṁ₀ = 10^-7 M_⊙/year, α = 0.1. Middle panel: Ṁ₀ = 3 × 10^-8 M_⊙/year, α = 0.3. Lower panel: Ṁ₀ = 10^-8 M_⊙/year, α = 0.3.
