VizieR Online Data Catalog: Abundances of classical Cepheids (Acharova+, 2012)

In the present paper, we use the most extensive spectroscopic (only) data on oxygen and iron abundances derived for 282 classical Cepheids (872 spectra in total). Some of the data were previously published (Luck et al. 2011, Cat. J/AJ/142/51, and references therein).

The spectra of additional Cepheids were obtained using the facilities of the 1.93-m telescope at the Haute-Provence Observatoire (France) equipped with echelle spectrograph ELODIE. Some spectra of Cepheids were obtained with the fibre echelle spectrograph HERMES mounted on the 1.2-m Belgian telescope on La Palma. We also made use of spectra obtained with the Ultraviolet-Visual Echelle Spectrograph (UVES) instrument at the Very Large Telescope (VLT) Unit 2 Kueyen.
