- Abstract
O-rich SRa and SRb variables have been observed in the 12CO(1-0) and (2-1) lines. A total of 40 stars were observed and 19 detections can be reported. The majority of the objects are weak in CO and have envelopes with small expansion velocities between 1.9 to 15.6 km/s. No correlation is found between period and expansion velocity for the short period objects whereas a trend may be present for the long period ones.
