CONTINUUM EMISSION ASSOCIATED WITH 6.7-GHZ METHANOL MASERS

We have used the Australia Telescope Compact Array (ATCA) to search fo r continuum emission toward three strong 6.7-GHz methanol maser source s. For two of the sources, G 339.88 - 1.26 and NGC 6334F (G 351.42+0.6 4), we detect continuum emission closely associated with the methanol masers. A further three clusters of masers show no radio continuum emi ssion above our sensitivity limit of 1-5 mJy. We find the position of the 6.7-GHz methanol masers in G 339.88 - 1.26 to be consistent with t he hypothesis that the masers lie in the circumstellar disc surroundin g a massive star. We also argue that one of the clusters of methanol m asers in NGC 6334F provides indirect observational support for the cir cumstellar disc hypothesis.
