Observational studies of high-mass young stellar objects (HMYSOs) at radio wavelengths are necessary to answer the question about high-mass star formation. Significant contributions to our knowledge of the formation of HMYSOs come from interferometric observations of cosmic masers, mainly OH, methanol, and water transitions.
We imaged a sample of 12 sources where the excited OH maser line at 6.035 GHz exists and the 6.7 GHz methanol maser line using e-MERLIN. We present preliminary results for the first three targets, well-known high-mass star-forming regions. We have found the coincidence of maser clouds at both transitions and their avoidance. That allows us to put constraints on the local physical conditions in the close surroundings of HMYSOs.
The first look at the coincidence of methanol and excited OH masers around HMYSOs
