Abstract:
The non-LTE sodium abundances of 100 dwarf, giant and subgiant stars
with metallicities -3<[Fe/H]<0.3 are determined using high-dispersion
spectra with high signal-to-noise ratios.
Description:
Spectra of the stars were obtained on the 1.93-m telescope of the
Haute Provence Observatory equipped with the ELODIE echelle
spectrometer. The resolution of the spectrometer was 42000,the
wavelength range observed was λλ4400-6800Å, and the
resulting signal-to-noise ratios were 130-230.
