Description

Core-collapse supernovae early in the Galactic history are sites for heavy element formation, enriching the oldest observable stars in the Galaxy. High-resolution spectroscopic observations have revealed a subset of old stars that exhibit enhanced abundances of elements between strontium and silver (Z=38-47) that cannot be explained solely by currently accepted models. This work aims to identify these stars in existing databases and constrain the astrophysical mechanisms responsible for producing these enhanced abundances.
