| Abstract: |
Preliminary results of high-resolution optical spectral analysis of
two carbon-rich long-term variables, V1983 Cyg and V2047 Cyg, are
presented. The stars were suspected to be cool R CrB variables
according to their photometric light curves, although our
spectroscopic study suggests that both stars are more similar to
ordinary N-type carbon stars. For V1983 Cyg, possible absorption
in the Balmer lines is detected. |
