VizieR Online Data Catalog: Carbon and oxygen in 107 dwarf stars (Pavlenko+, 2019)
Abstract
We used the observed spectra obtained in the framework of the Calan-Hertfordshire Extrasolar Planet Search (CHEPS) programme (Jenkins et al., 2009ApJ...704..975J, Cat. J/ApJ/704/975).
All stars in our work were observed with the HARPS spectrograph (Mayor et al., 2003Msngr.114...20M) at a resolving power of 115,000, and since the spectra were taken as part of the CHEPS programme, whose primary goal is the detection of small planets orbiting these stars, the S/N of the spectra are all over 100 at a wavelength of 6000Å. The 107 stars in this work are primary targets for CHEPS. Carbon and Oxygen in the CHEPS stars. Cases of the problematic determination of oxygen abundance due to the strong blending 6300.304Å OI line by telluric lines are marked by (*). The oxygen abundances determined by visual comparison of computed and observed spectra are marked by (+). (1 data file).- Publication:
