Supernovae from stellar mergers and accretors of binary mass transfer: Implications for Type IIP, 1987A-like and interacting supernovae

Fig. 7.

Similar to Fig. 6 but showing the ejected nickel mass, M_Ni, as a function of logarithmic explosion-energy to ejecta-mass ratio, E_expl/M_ej. The E_expl/M_ej ratio is a measure of the average SN ejecta velocity, $v_{sn} = \sqrt{2 E_{expl} / M_{ej}}$ $v_{\mathrm{sn}} = \sqrt{2E_{\mathrm{expl}}/M_{\mathrm{ej}}}$ , shown on the top x-axis. Black crosses are for models likely experiencing significant LBV-like mass loss.
