Terminal velocity to escape velocity ratio for our sample stripped stars: For comparison, we also plotted the v_∞/v_esc, Γ ratios observed for OB stars. The black dashed lines represent v_∞/v_esc, Γ for Galactic OB stars as reported in the study by Lamers et al. (1995). The ratios are different for stars with T_* ≳ 21 kK (blue region) for stars cooler than 21 kK (red region). The green dashed lines represent the same ratio but scaled to SMC metallicity, as described in Leitherer et al. (1992), whereas the magenta dashed lines indicate a steeper metallicity scaling found by Vink & Sander (2021).
