Observations of OH 4765-MHz maser emission from star-forming regions.

SZYMCZAK M., KUS A.J. and HRYNEK G.

Abstract (from CDS):

We report observations of the 4765-MHz maser transition of OH (2Π1/2, J=1/2, F=1⟶0) towards 57 star-forming regions, taken with the 32-m Toru{nacute} telescope. Nine maser sources were detected, of which two had not been reported previously. The newly discovered sources in W75N and Cep A and four previously known sources were monitored over periods ranging from a few weeks to six months. Significant variations of the maser intensity occurred on time-scales of one week to two months. The relationships between the flux density and the linewidth for the new sources, established during the rise and fall phases of bursts that lasted 6-8 weeks, are consistent with a model of saturated masers.
