Description:
We present a survey for OH maser emission at 18cm in the direction of
196 IRAS point sources. The primary aim of the survey was to detect OH
maser emission from post-asymptotic giant branch (post-AGB) stars. OH
emission and/or absorption was detected in the direction of 77 sources
of which 57 OH detections were previously unknown, giving an overall
detection rate of 39 per cent. Fourteen maser sources associated with
evolved stars or planetary nebulae were found, corresponding to 7 per
cent of the total observed. These included three planetary nebulae
(two new OH detections), nine post-AGB stars (three new OH detections)
and two cold OH/IR stars (both previously known). Two sources were of
uncertain identification (both new OH detections). The remainder of
the OH sources were identified with young stellar objects and with HII
regions. The survey included the detection of OH maser emission from
HD 101584, an early-type supergiant at high Galactic latitude. For
several of the post-AGB stars, changes have occurred in the OH
spectral profiles over a period of several years. This is interpreted
as evidence for rapid changes in the stellar winds, due either to
interactions with stellar companions, novae-like events or rapid
stellar evolution.
