cds-question@unistra.fropen-star-clusterseffective-temperaturechemical-abundancesvisible-astronomyspectroscopyOpen clusters are key chemical and age tracers of Milky Way evolution. While open clusters provide significant constraints on galaxy evolution, their use has been limited due to discrepancies in measuring abundances from different studies. We analyze medium-resolution (R~19000) Cerro Tololo Inter-American Observatory/Hydra spectra of giant stars in 58 open clusters using The Cannon to determine [Fe/H], [Mg/Fe], [Si/Fe], [Al/Fe], and [O/Fe]. This work adds an additional 55 primarily southern hemisphere open clusters calibrated to the Sloan Digital Sky Survey/Apache Point Observatory Galactic Evolution Experiment DR16 metallicity system. This uniform analysis is compared to previous studies [Fe/H] measurements for 23 clusters and we present spectroscopic metallicities for the first time for 35 open clusters.2022AJ....163..195Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/163/195CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)V/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)J/A+A/480/79 : Abundances of giants in 5 Galactic clusters (Bragaglia+, 2008)J/AJ/136/118 : Open clusters as galactic disk tracers.
