A search for OH emission from symbiotic stars.
Abstract
The results of a sensitive search for OH maser emission from a sample of 16 symbiotic stars are presented. The sample was selected on the basis of infrared optical depth and variability, so that the selected stars would have circumstellar shells similar to OH/IR and OH/Mira stars. No maser emission was detected, except for one unassociated background source near BI Cru. On the basis of the observational data, it is suggested that the presence of a hot binary companion inhibits any possible maser action.
