Scientific paper
The primary aims of this proposal are to find young high-mass stars still in the process of accreting material and to improve our knowledge of the structure of our Galaxy. We are proposing a new method to directly detect infalling molecular gas through proper motion VLBI observations of methanol masers. 6.7 GHz methanol masers are considered one of the best tracers of the earliest stages of high-mass star formation. Recent observations have found indirect evidence that some of the young stellar objects associated with methanol masers may be at the infall stage and hence still in the process accreting their final mass. These observations will also yield the distance to the masers sources through measurement of the parallax. Combining the results of this project with parallax observations of 12.2 GHz methanol masers with the VLBA will enable an accurate rotation curve for the Galaxy to be determined and hence the enclosed mass as a function of Galactocentric radius.
