J/PASJ/57/65      CNO abundances of solar-type stars       (Takeda+, 2005)

Photospheric CNO abundances of solar-type stars. Takeda Y., Honda S. <Publ. Astron. Soc. Jap., 57, 65-82 (2005)> =2005PASJ...57...65T
ADC_Keywords: Stars, nearby ; Abundances ; Equivalent widths Keywords: line: formation - stars: abundances - stars: atmospheres - stars: late-type - stars: planetary systems 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 File Summary:
