Evolution of the semimajor axis (top), eccentricity (middle), and both the mass ratio q and angle ℰ (bottom) as a function of time for different AML modes for our example model of a 26 M_⊙ donor with a 10 M_⊙ accreting BH companion (point-mass limit). The orange, blue, and red lines correspond to the isotropic reemission, Jeans, and orbital-AML modes, respectively. The black and gray lines represent the L₂ mass-loss mode for β = 0 (fully nonconservative MT) and β = 0.91 (highly conservative MT), respectively. For all models f_don = 1. In the bottom subfigure, the two horizontal dotted lines indicate ℰ₀ = π and q = 1.
