Spectrophotometry of carbon stars. III. Molecular absorption bands: Quantitative analysis

The C2, CN, SiC2, and CH molecular absorption bands of 56 carbon stars are analyzed quantitatively on the basis of the spectroscopic observations reported by Ogansian et al. (1985); the results are presented in tables and graphs. Features noted include a separation of early and late stars in the C2...

Beschreibung
Zusammenfassung:	The C2, CN, SiC2, and CH molecular absorption bands of 56 carbon stars are analyzed quantitatively on the basis of the spectroscopic observations reported by Ogansian et al. (1985); the results are presented in tables and graphs. Features noted include a separation of early and late stars in the C2 Swan-system red /blue index diagram, a separation of R and N stars in the (C-12)N /(C-13)N index diagram, and a correlation between the 4976-A Merrill-Sanford band and the 5896/5890-A Na I doublet.
