Chemical abundances in the metal-intermediate GC NGC 6723

Crestani, Juliana; Alves-Brito, A; Bono, G; Alencastro Puls, Arthur; Alonso-Garcia, Javier

Description

We have performed a detailed spectral analysis of the inner halo Galactic globular cluster (GC) NGC 6723 using high-resolution (R ≈ 22 000–48 000) spectra for for 11 red giant branch stars collected with MIKE (Magellan) and FEROS (MPG/ESO). This globular is located at the minimum of the bimodal metallicity distribution of GCs, which suggests that it might be an excellent transitional system between metal-intermediate and metal-rich GCs. In spite of its metal-intermediate status, it is...[Show more]
