The Gaia BH3 companion exhibits an r-I abundance pattern reproduced by core-collapse supernova plus r-process yields and closely matching diluted ED-2 stars, supporting early cluster enrichment over local pollution.

NLTE analysis finds F_odd of 0.65 in one CEMP-rs star versus 0.23 in two CEMP-s stars, supporting distinct isotope ratios as a signature of different neutron-capture processes.
Spectroscopic abundances of s-elements in AGB stars provide important constraints on theoretical models of stellar nucleosynthesis and mixing.
