VizieR Online Data Catalog: LMC classical Cepheids Fe and O content (Romaniello+, 2022)
Abstract
We assembled our sample of 89 Classical Cepheids in the LMC by combining proprietary data for 67 out of the 70 stars that define the SH0ES fiducial PL relation (Riess et al., 2019ApJ...876...85R, Cat. J/ApJ/876/85) with 22 archival spectra observed in the same instrumental setup. For the mentioned sample of 67 stars, this is the first measurement of their chemical composition. Iron abundances for the other ones were published by Romaniello et al. (2008A&A...488..731R, OGLE510/HV879 is in common between the two samples and is considered here only once).
