Three-dimensional Supernova Models Provide New Insights into the Origins of Stardust

We present the isotope yields of two post-explosion, three-dimensional 15 $M_\odot$ core-collapse supernova models, 15S and 15A, compare them to carbon, nitrogen, silicon, aluminum, sulfur, calcium, titanium, iron, nickel isotopic compositions SiC stardust. find that these models predict similar carbon nitrogen X grains with $^{12}$C/$^{13}$C $<$ 20 $^{14}$N/$^{15}$N 60, which we will hereafter refer as 'D' grains. Material from interior a explosion reaches high enough temperatures shortly after core collapse produce large enrichments $^{13}$C $^{15}$N necessary replicate D The innermost ejecta in is operating neutrino-driven regime undergoes fast proton capture being heated by shockwave. Both 3-D 0.3 $^{26}$Al/$^{27}$Al 1.5, comparable ratios seen X, C, Models general, very anomalies calcium isotopes but do qualitatively grain measurements show $^{44}$Ca $^{43}$Ca excesses. titanium are well reproduced. $^{57}$Fe excesses depletions observed grains, addition accurately $^{60}$Ni/$^{58}$Ni, $^{61}$Ni/$^{58}$Ni, $^{62}$Ni/$^{58}$Ni result neutron captures initiated propagation Finally, symmetry has noticeable effect on production iron SN ejecta.
