Evolution of essential binary interaction parameters for two sets of representative model sequences. Color indicates the initial orbital period (P_init) of the system. Lines of the same color are valid for the same initial orbital period. R_RL,d, represented by the bold lines, is the radius of the donor star’s Roche lobe. Ṁ is the mass transfer rate, represented by the thin dash-dotted lines. The radius of the donor star, R_d, is represented by the thick black line. Each plot shows all model sequences obtained for the entire range of initial orbital periods for a single pair of initial donor star (M_d,i) and WD (M_WD,i) masses. The parameters chosen for panel (A) are M_d,i = 0.55 M_⊙ and M_WD,i = 1.10 M_⊙ and for panel (B)M_d,i = 0.65 M_⊙ and M_WD,i = 1.10 M_⊙. Obtained outcomes are indicated by the rectangles. We note that in graph (B), the systems with P_init = 0.06 d (see Fig. 3) and P_init = 0.065 d (see Fig. 5), have been left out for clarity.
