Abstract
Peculiar profiles were discovered in EY And, one of five new sources found in an OH maser search. The 1612-MHz emission has a typical, double-peak structure, but the main-line masers show polarized features at the central velocity of the 1612-MHz emission. The line shape of the SiO maser resembles that of the 1665-MHz emission. Maser sources with polarized OH emission at intermediate velocities are discussed in the context of two kinematic models. Expanding envelopes with a smooth velocity field would require some of the polarized OH features to arise in the innermost part of the envelopes. Distortion of a smooth outflow by interaction with the ambient gas cannot explain the peculiar OH emission. It is interpreted as a fluctuation of the velocity field of the expanding envelope. The polarized features in both main-line spectra have the same sense of circular polarization when they appear at nearly the same velocity. This evidence is consistent with the mechanism proposed by Cook and Shklovskii.
