Evolution of a 2.0+1.0 M_⊙ binary with initial period P_i = 8000 d and eccentricity e_i = 0.1 using the parameter set AV6. We present, as a function of the primary mass M₁, (a) the orbital period, P_orb; (b) the eccentricity e; (c) the Roche-filling factor $R_1/R_{L_1}$; (d) the primary mass loss rates from the wind ${\dot{M}}_{\text{wind}}$ (dashed curve) and RLOF ${\dot{M}}_{\text{RLOF}}$ (solid curve); (e) the surface density at the CB disk's inner rim, Σ_in; (f) the change in the orbital eccentricity ė (black curve), which is decomposed into contributions from the CB disk (orange), tides (red), RLOF (green). The evolution of the system is divided into different stages, labeled S1–S5, and separated by the vertical black dotted lines.
