The s- and r- components of the proto-solar composition
arXiv:2605.23690
Abstract
We present a brief overview of the various methods proposed to derive the s- and r-components of the proto-solar chemical composition and we discuss some recent developments in the field, including the impact of rotating massive stars, nuclear measurements, physics of low mass asymptotic giant branch stars, isotopic composition of presolar SiC grains and new derivations.
