Top panel: a comparison of our analytic model for the distribution of ejection velocities (Equation (7), shown in black) to our fiducial simulation for the subset of SN progenitors that are ejected with v_ej ≥ 5 km s⁻¹ (shown in red, with the lower-velocity region shaded in gray). Bottom panel: the metallicity dependence of our analytic model for the ejection velocity distribution. Lower-metallicity binaries typically produce higher ejection velocities. An interactive version of this data is available in Figure 9.
