Abstract:
We present homogeneous and accurate iron abundances for almost four
dozen (47) of Galactic Cepheids using high-spectral resolution
(R∼40000) high signal-to-noise ratio (S/N≥100) optical spectra
collected with UVES at VLT. A significant fraction of the sample (32)
is located in the inner disk (RG≤6.9kpc) and for half of them we
provide new iron abundances.
Description:
Iron line list (FeI and FeII) used in this analysis for iron abundance
estimates. For each line the Table gives from left to right the
wavelength, the ion identification, the excitation potential (EP) and
the loggf values.
