Comparison between Core-collapse Supernova Nucleosynthesis and Meteoric Stardust Grains: Investigating Magnesium, Aluminium, and Chromium

Abstract Isotope variations of nucleosynthetic origin among solar system solid samples are well documented, yet the these is still uncertain. The observed variability 54 Cr materials formed in different regions protoplanetary disk has been attributed to variable amounts presolar, chromium-rich oxide (chromite) grains, which exist within meteoritic stardust inventory and most likely originated from some type supernova explosion. To investigate if core-collapse supernovae (CCSNe) could be site we analyze yields CCSN models stars with initial masses 15, 20, 25 M ? , metallicity. We present an extensive abundance data set Cr, Mg, Al isotopes as a function enclosed mass. find cases explosive C ashes produce composition good agreement Cr/ 52 53 ratios 50 ratios. Taking into account that signal at atomic mass also originate Ti, He burning match Addition material (enriched relative Mg simulate make-up chromite grains) system’s may reproduce correlation between anomalies, while does not significant anomalies together isotopic variations. In all cases, nonradiogenic, stable isotope dominate over expected 26 Al.
