Scientific paper

The paper reports the detection of CO emission from seven late-type stars selected from the sources observed by the IRAS low resolution spectrometer to have 11 micron SiC features. All the resources have no existing catalog associations and are typically 10 times weaker at 12 microns than previously detected radio carbon stars. They are considered to be excellent candidates for hitherto unidentified carbon stars. Comparison of these objects with IRC + 10216 suggests that the distance to IRC + 10216 may have been overestimated in the past.
