VizieR Online Data Catalog: α-element abundances of Cepheid stars (Genovali+, 2015)

The abundances of Fe, Na, Al, and three alpha elements (Mg, Si, Ca) for our sample of 75 Cepheids plus data available in the literature for other 364 Cepheids are shown. We first show the abundances derived based on individual spectra for the 75 stars, then the averaged values, and finally the data from the literature. The original abundances available in the literature were rescaled according to the zero-point differences listed in Table 3. The priority was given in the following order: we first adopt the abundances provided by our group, this study (TS) and Lemasle et al. (2013A&A...558A..31L, LEM), and then those provided by the other studies, Luck & Lambert (2011AJ....142..136L, LIII), Luck et al. (2011AJ....142...51L, LII), and Yong et al. (2006AJ....131.2256Y, YON).
