Key Points

Chemical abundances of cobalt and copper were analyzed to determine their production processes.
Neutron-capture processes show secondary behaviours, while alpha-rich freeze-out processes exhibit primary behaviours.
The study compares findings from bulge and halo stars against theoretical chemical evolution models.
Understanding the production mechanisms of cobalt and copper enhances knowledge of stellar evolution.

Abstract

Chemical abundances of cobalt (Co; Z = 27) and copper (Cu; Z = 29) in bulge and halo stars are presented and compared with chemical evolution models. The aim is to distinguish if Co and Cu are dominantly produced by neutron-capture or the alpha-rich freeze-out processes. Neutron-capture can be identified by a secondary behaviour in the [X/Fe] vs. [Fe/H] plot, and alpha-rich freeze-out would give rather a primary behaviour.
