Mass accretion rates, photoevaporative mass loss rates, and MHD-wind-driven mass loss rates for discs of different initial sizes and with different values of ψDW, namely ψDW = 0 (purely viscous disc, dotted lines), ψDW = 1 (hybrid disc, dashed lines), and ψDW ≫ 1 (purely MHD-wind disc, continuous lines). For explanatory purposes we consider here high irradiation, 1000 G0, and low-to-moderate total αtot = 10−4–10−3. The vertical dashed purple lines represent the gas disc lifetime diagnostic tdep,gas (see Sect. 3.3).
