J/AZh/80/458        Sodium abundances in stellar atmospheres  (Mishenina+, 2003)

Sodium abundances in in stellar atmospheres with differing metallicities. Mishenina T.V., Kovtyukh V.V., Korotin S.A., Soubiran C. <Astron. Zh. 80, 458 (2003)> =2003AZh....80..458M =2003ARep...47..422M
ADC_Keywords: Stars, atmospheres; Abundances, peculiar 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. File Summary:
