Abundance anomalies in NGC 2808

Authors: G. Pace, A. Recio-Blanco, G. Piotto, Y. Momany
Comments: 11 pages, 7 figures, accepted by A&A

“We present metallicity measurements of 25 stars in the blue horizontal branch of the Galactic globular cluster NGC 2808. Our measurements are based on moderate-resolution spectra taken with the multi-object fiber facility FLAMES-UVES, mounted on Kueyen at the Very Large Telescope. We confirm that stars hotter than a threshold temperature have super-solar abundance, while the cooler ones respect the nominal metallicity of the cluster, i.e. [Fe/H] ~ -1.1….”
