Figure 12: Profiles of temperature, optical depth, ratio of scale height to radius, and advection factor (the ratio of advective cooling to turbulent heating) of a hot, one-T ADAF (solid lines). The parameters are M = 10M ⊙, M˙ = 10−5LEdd ∕c2, α = 0.3, and β = Pgas∕(Pgas + Pmag) = 0.9. The outer boundary conditions are Rout = 103RS, T = 109 K, and v∕cs = 0.5. Two-T solutions with the same parameters and δ = 0.5 (dashed lines) and 0.01 (dot-dashed lines) are also shown for comparison, where δ is the fraction of the turbulent viscous energy that directly heats the electrons.
