Subgiant CH stars. I. s-process abundances, C/O ratios, and evolutionary status
Description
Subgiant CH stars are late F to early G stars showing enhanced CH and Sr ii features on low-dispersion spectrograms. In this paper we report abundance analyses of seven relatively bright subgiant CH stars and the red-giant CH star HD 26, based on Palomar and Mount Wilson photographic coude spectrograms in the blue spectral region and on Mount Wilson coude scans in the red region
