Abstract

The copious mass loss which takes place at late stages of stellar evolution, while a star is on the AGB, causes the formation of a cool extended circumstellar envelope expanding at speeds like 15 km s−1. These envelopes are observed in many molecular lines, which give the stellar velocity, the wind velocity and an estimate of the mass loss rate.
