On the unidentified bands 6830-7088 in symbiotic stars.
Abstract
A strong broad emission feature has been noted by various investigators in the red spectra of about 60 stars, centered at wavelengths of 6830 and 7088 A. The stars are all classified as symbiotic, since they combine high-excitation emission and M-type absorption spectra. In the present paper, a historical review is followed by a discussion of new observational data. A search for identification is conducted, and the diagnostic opportunities afforded by these two bands are examined.
