Evolutionary diagrams comparing orbital period (P_orb) and donor star properties for five MB prescriptions. Left panels: Relationship between P_orb and donor mass (M_donor). Right panels: Corresponding donor radius (R_donor) versus mass evolution. In panels (a) and (b), we show M_donor, i = 0.6 M_⊙ + M_WD, i = 0.6 M_⊙ (solid lines) and M_donor, i = 0.6 M_⊙ + M_WD, i = 1.0 M_⊙ (dashed). (b) In panels (c) and (d) we show M_donor, i = 1.2 M_⊙ + M_WD, i = 0.6 M_⊙ (solid) and M_donor, i = 1.2 M_⊙ + M_WD, i = 1.0 M_⊙ (dashed). All models share initial orbital period P_orb, i = 0.4 d. Observed systems from McAllister et al. (2019) are marked with purple stars.
