Hoppe, P., Stancliffe, R. J., Pignatari, M., & Amari, S. (2019). Isotopic Signatures of Supernova Nucleosynthesis in Presolar Silicon Carbide Grains of Type AB with Supersolar 14N/15N Ratios. The Astrophysical journal, 887(1), 10. https://doi.org/10.3847/1538-4357/ab521c

We report high-resolution C, N, Al, Si, and S isotope data of 38 presolar SiC grains of type AB. Seventeen of these grains are of subtype AB1 (14N/15N < 440 = solar) and 20 of subtype AB2 (14N/15N ≥ 440), previously proposed to be mainly from superno...
