Abstract:
C and O abundances are determined for 151 F and G main-sequence stars
with metallicities in the range -1.6<[Fe/H]<+0.4. The C abundances are
determined from the CI lines at 5052 and 5380Å and oxygen
abundances from the OI triplet at 7774Å and the forbidden [OI] line
at 6300Å.
Description:
Equivalent widths of C and O lines and the abundances derived are
given for 66 disk stars with ESO3.6m/HARPS and ESO2.2m/FEROS spectra
and for 85 halo and thick-disk stars with ESO-VLT/UVES or NOT/FIES
spectra available in the ESO Science Archive.
