Scientific paper

A survey of potential SiO maser sources has been made using the Parkes radio telescope operating at 43 GHz. The candidate objects were all bright southern IRAS sources and were selected using criteria developed for use in an earlier study. A further 29 masers were discovered in the present survey and, for most of these sources, data in both v = 1 and v = 2 (J = 1-0) transitions were obtained. Although many of the candidate IRAS sources have not been observed at visual wavelengths, there are published optical variability data for nine objects. In these cases the relationship between SiO maser emission and visual amplitude, proposed previously, is not violated. It is suggested that, in the main, the new masers are associated with optically obscured Mira variables. This paper also presents the latest 43-GHz maser polarization spectra for the nearest symbiotic binary, R Aqr, and for GL 5552, the most intense source discovered in an earlier survey.
