Supergiant GCIRS 22 in the Milky Way nuclear star cluster : Revised alpha abundances
Context. The chemical abundances of alpha elements in Galactic Centre (GC) supergiants provide key insights into the chemical enrichment and star formation history of the Milky Way’s nuclear star cluster. Previous studies have reported enhanced alpha-element abundances, which raises questions about the chemical evolution of this unique region. Aims. We aim to reassess the alpha-element abundances
