Different timescales as a function of the radius in the disc, using the disc parameters of one of our simulations, v_ISM = 3 km s^-1 and ρ_ISM = 1.9 × 10^-19 g/cm³. This is the case with the longest accretion timescale, τ_ṁ, which is not in the regime where Bondi-Hoyle accretion dominates. The dashed line is the timescale on which mass is loaded on the disc (see Eq. (8)) and the solid line represents the viscous timescale (see Eq. (7)).
