Comparison of our results (shown in solid lines) with the results from Gallet et al. (2019; shown in dashed lines) expressed in our units of J_⋆ (top). The line colors correspond to the same magnetic field strengths in both solid and dashed lines. In the leftmost panel, K_acc = 1 was set in Eq. (12), and K₁ = 1.7 and K₂ = 0.0506, m = 0.2177 in Eqs. (9) and (10). The results from our simulations differ from Gallet et al. (2019) predictions, in which they assumed those factors to be constant. In our simulations, those quantities are self-consistently adjusting. Examples of curves (bottom) for the same models by Gallet et al. (2019) as in the top panels (shown with the dashed lines) with the accretion factors K_acc, K_ME, and K₁ modified in such a way to (at least in some of the solutions) better match the results from our simulations, shown with the solid lines. The text gives details on the modifications.
