Abstract:
We determined the C, N, and O abundances of 160 nearby F, G, and K
dwarfs and subgiants by using spectra obtained with the HIDES
spectrograph at Okayama Astrophysical Observatory, with the purposes
of (1) establishing the runs of [C/Fe], [N/Fe], and [O/Fe] for these
galactic disk stars in the metallicity range of -1≲[Fe/H]~<+0.4, (2)
searching for any difference in the CNO abundances of planet-host
stars as compared to non-planet-host stars, and (3) examining the
consistency of the abundances derived from different lines to check
the validity of the analysis. The non-LTE effect on the abundance
determination was taken into consideration based on our extensive
statistical-equilibrium calculations.
Description:
The detailed results of our CNO abundance analyses; i.e., the
equivalent widths, the atmospheric parameters, and the resulting
abundances and the NLTE corrections are in files *abund.dat
