Circinus galaxy: mass accretion rate of the thick gas disk (in M_⊙ yr⁻¹) as a functionof the Toomre Q parameter. Each point corresponds to a given critical radius where the wind sets in and the accretion disk becomes thin. Each line corresponds to a velocity dispersion of v_turb = 10, 20, 30, 40, 50, 60, and 70 km s⁻¹ (from left to right). The critical radii range from 0.2 pc (blue) to 3 pc (red) in steps of 0.1 pc. Triangles: p_rad∕p_B < 0.5; boxes: p_rad∕p_B ≥ 0.5. The intersection of the solid lines corresponds to the assumed critical radius r_wind = 0.53 pc and v_turb = 30 km s⁻¹.
