Nucleosynthesis of light trans-Fe isotopes in ccSNe: Implications from presolar SiC-X grains

abstract

This talk presents an r-process parameter study within the high-entropy-wind (HEW) scenario of core-collapse supernovae (ccSNe). One of the primary aims of this study was to obtain indications for theproduction of classical p-, s- and r-isotopes of the light trans-Fe elements in the Solar System (S.S.). Here,we focus on the nucleosynthesis origin of the anomalous isotopic compositions of Zr, Mo and Ru in presolarSiC X-grains (SNe grains). In contrast to the interpretation of other groups, we show that these grains donot represent the signatures of a 'clean' stellar scenario, but rather, are mixtures of an exoticnucleosynthesis component and S.S. material
