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, and compare them to the carbon, nitrogen, silicon, aluminum, sulfur, calcium, titanium, iron, and nickel isotopic compositions of SiC stardust. We find that these core-c...

Description
Summary:We present the isotope yields of two post-explosion, three-dimensional 15 \(M_\odot\) core-collapse supernova models, 15S and 15A, and compare them to the carbon, nitrogen, silicon, aluminum, sulfur, calcium, titanium, iron, and nickel isotopic compositions of SiC stardust. We find that these core-collapse supernova models predict similar carbon and nitrogen compositions to SiC X grains and grains with \(^{12}\)C/\(^{13}\)C \(
