Effect of SN-kicks on the delay time distributions of NS–WD mergers for different CE models. The rate is minimized for the large SN kicks of the Hobbs-distribution (blue solid line) and the Arzoumanian-distribution (green dashed line). If the SN kick is only due to the instantaneous mass loss (Blaauw-kick, red dashed line), the rate is maximized. The different panels show the DTDs from different CE models; model αα on top, model αα2 in the middle, and model γα on the bottom. See also Fig. 5 for a direct comparison of the DTDs from the CE models.
