HR diagrams for the 0.64 M_⊙ model. [Top Panel] Evolutionary track of the 0.64 M_⊙ model relaxed directly to the remnant profile and the model relaxed to donor profile and then heated. Red lines show lines of constant radii from 0.01 − 0.3 R_⊙. Only ∼0.001% of the total evolutionary time is spent above R > 0.03 R_⊙, without considering the helium flash. [Bottom Panel] Comparison plot of the model without any helium in the inner layers of the star.
