Impact of binary-stripped star wind variations on the central mass fractions at the moment of core helium depletion. Open and filled crosses indicate the central mass fractions of ¹⁶O and ¹²C, respectively. Gray crosses show variations for binary-stripped star models when we decrease the strength of the winds after Roche-lobe overflow by a constant factor, indicated on top of the vertical lines. For reference, we show a single (light blue) and binary-stripped (red) star model with the same initial mass of 11 M_⊙ (top panel) and 20 M_⊙ (bottom panel). In the bottom panel, we also compare the binary-stripped star models to a single-star model with the same reference core mass of 6.3 M_⊙ with an initial mass of 16 M_⊙.
