Ejecta profiles for the models used as part of this work. Density profiles are shown in mass- (panel a) and velocity-space (panel b). Panel c: ⁵⁶Ni distributions are shown for the EXP_KE1.10 density profiles with 0.4, 0.6, and 0.8 M_⊙ of ⁵⁶Ni. Density profiles and ⁵⁶Ni distributions are shown for a selection of explosion models: W7 (pure deflagration; Nomoto et al. 1984), DDT N100 (deflagration-to-detonation transition; Seitenzahl et al. 2013), DEF N1600 (pure deflagration; Fink et al. 2014), VM (violent merger; Pakmor et al. 2012).
