VizieR Online Data Catalog: 885 globular cluster giants abundances (Masseron+, 2019)
Abstract
We investigated the abundances of ten elements (C, N, O, Mg, Al, Si, K, and Ca, Ce and Nd), for 885 stars in 10 globular clusters (NGC 7078, NGC 6341, NGC 5024, NGC 5466, NGC 6205, NGC 7089, NGC 5272, NGC 5904, NGC 6171, and NGC 6838) using Apache Point Observatory Galactic Evolution Experiment (APOGEE; Majewski et al. 2015, Cat. J/AJ/149/7) DR14 spectra. We make use of photometry and theoretical isochrones to constrain the effective temperature (Teff) and surface gravity log(g) and the stellar evolutionnary status (RGB, HB, or early AGB). The abundances are derived by line fitting with the automatic code BACCHUS (Masseron, Merle & Hawkins, 2016ascl.soft05004M), which uses MARCS model atmospheres andf the APOGEE DR14 atomic and molecular linelists.
