摘要：
Asymptotic Giant Branch stars (AGB) are evolved red giants with tenuous molecular envelopes that have been the subject of much recent study using infrared and radio interferometers. In oxygen-rich stars, radio SiO masers form in the outer regions of the molecular envelopes and are powerful probes of the extent and dynamics of these envelopes. We discuss recent IR and radio measurements that are providing a wealth of information on these systems.
