J/AJ/139/2034        NGC 6253 stars equivalent widths    (Anthony-Twarog+, 2010)

Wiyn open cluster study. XXXIX. Abundances in NGC 6253 from HYDRA spectroscopy of the Li 6708Å region. Anthony-Twarog B.J., Deliyannis C.P., Twarog B.A., Cummings J.D., Maderak R.M. <Astron. J., 139, 2034-2051 (2010)> =2010AJ....139.2034A
ADC_Keywords: Clusters, open ; Abundances ; Equivalent widths Keywords: open clusters and associations: individual (NGC 6253, NGC 6791) - stars: abundances - techniques: spectroscopic Abstract: High-dispersion spectra of 89 potential members of the old, super-metal-rich open cluster, NGC 6253, have been obtained with the HYDRA multi-object spectrograph. Based upon radial-velocity measurements alone, 47 stars at the turnoff of the cluster color-magnitude diagram (CMD) and 18 giants are identified as potential members. Description: Spectra of 89 stars in NGC 6253 were obtained in 2005, 2006, and 2007 with the Cerro Tololo Inter-American Observatory Blanco 4 m telescope equipped with the HYDRA multi-object spectrograph.
