Yong, DavidCarney, B WTeixera de Almeida, M.L.Pohl, B.L.2015-12-070004-6256http://hdl.handle.net/1885/24876We present metallicities, [Fe/H], and elemental abundance ratios, [X/Fe], for a sample of 24 Cepheids in the outer Galactic disk based on high-resolution echelle spectra. The sample members have galactocentric distances covering 12 kpc ≤ RGC ≤ 17.2 kpKeywords: Galaxy: abundances; Galaxy: diskElemental Abundance Ratios in Stars of the Outer Galactic Disk. III.
