Termination conditions of 26 M_⊙ and 62.5 M_⊙ models that use ET as function of the initial mass ratio q_init = M_2,init/M_1,init and initial period p_init. In color we indicate the models that experience L2OF at the ZAMS (light blue), those that experience L2OF during the main sequence (orange, “mergers”) or experience a MT rate above 10⁻¹ M_⊙ yr⁻¹ (dark blue), those that survive the main sequence without experiencing L2OF (yellow), and those terminate with a numerical error (red). Forward-hatched models experience contact during their main-sequence evolution, while backward-hatched models overflow their RL at the ZAMS. Outlined in white are five classes (“Class 0-IV”) of systems determined by their qualitative evolution (see Sect. 3.1).
