(a) Distribution of specific angular momentum (λ) and (b) heating in the system as a function of radius (log r), when viscosity assumed is relativistic (green, solid) and Newtonian (magenta, dotted). Panel b: we also compare the heating due to magnetic dissipation, Q_B (blue, dashed), assuming β_d = 0.02. The flow parameters are E = 1.0005, α_vis = 0.01, λ₀ = 2.60, Ṁ = 0.01 Ṁ_Edd, and M_BH = 10 M_⊙.
