Entropy profiles of the donor star after it loses different amounts of mass for varying δ_ov. The solid line represents δ_ov = 0.50, the dashed line δ_ov = 0.25, and the dotted line δ_ov = 0.00. Black, blue, red, and purple represent the donor losing masses △M = 0.0 M_⊙, △M = 0.8 M_⊙, △M = 1.1 M_⊙, and △M = 1.7 M_⊙, respectively. The initial parameters are M_WDⁱ = 1.1 M_⊙, M₂ⁱ = 3.4 M_⊙, and log Pⁱ(days) = 0.5.
