Scientific paper

A dozen very red stars in the 2 microns IRC catalog for carbon monoxide emission are surveyed. The J = 1 approaching 0 transition of CO was detected toward the oxygen-rich giants IRC-10529, IRC + 40004, IRC + 10365, and probably IRC + 70066. These results are compared with previous observations of molecular envelopes around other late-type giant stars. Mira and CIT 6, two known and possibly variable CO emission sources, were also observed. SO and SO2, two molecules predicted to be abundant in models of circumstellar envelopes of Scalo and Slavsky, were not detected in the M-type variables W Hya, RX Boo, and R Cas.
