Outcomes of binary systems with a fixed mass ratio of q = 0.4 and different initial orbital periods and primary star masses. The gray squares represent systems with MT rates higher than 10 M_⊙ yr⁻¹, which we consider as dynamically unstable, the cyan squares represent systems that overflow the second Lagrangian point L₂, and the green squares represent models that are overflowing at the zero-age MS (ZAMS). The blue squares represent systems that undergo the Case-A MT, red squares represent systems that undergo the CHE, and orange squares represent models with numerical errors and where the simulation was not completed.
