説明

Curve-of-growth analyses were made for the coolest BaII star HD 121447 and the CS star R CMi using absolute gf-values, and the atmospheric parameters and relative abundances of fourteen elements were determined. The results are in accordance with those by curve-of-growth analyses with respect to ζ Cap, though the errors are somewhat larger. The spectra of these two stars are similar to those of cool carbon stars, but the molecular bands are much weaker. Line blending in cool carbon stars, therefore, can be corrected by comparing with the spectra of these two stars.
