As Fig. 5 for different accretion-efficiency and angular-momentum-loss prescriptions. Model set M2 adopts the WRLOF model of wind accretion and assumes isotropic wind mass loss. Model set M10 (dotted magenta line) is computed with Eq. (4) and γ = 2, and adopts the BHL model with α = 1.5. Model sets M15 and M16 (dot-dashed blue and dashed green lines, respectively) compute wind accretion efficiency with α = 10 within the BHL model. Set M15 assumes isotropic wind mass loss, whereas set M16 uses Eq. (4) with γ = 2.
