CO in the infrared and radio spectra of carbon stars.
Abstract
Spectral scans from 2.0 to 2.5 of many of the reddest sources in the Two-Micron Sky Survey have resulted in the identification of eight new carbon stars, five of which have subsequently been identified by other observers. These and other known carbon stars have been searched for 2.6-mm CO emission. A broad emission line, similar to that in IRC+ 10216, has been found in IRC +40540. IRC -20131 and IRC +50338 (V Cyg) show narrow CO lines whose origin is probably interstellar. Subject headings: carbon stars - infrared sources - molecules
