abstract:
Extensive observing campaigns of the 6.7 GHz methanol maser line have been carried out using single dishes in only a few observatories around the world.
Among them, the 32-m Torun radio telescope uniquely has been monitoring the high-mass star-forming regions in the Galactic plane for over a decade. It has been shown recently, that outbursts and flares of the methanol maser transition give a unique opportunity to investigate the accretion process in high-mass protostars. Under the international collaboration M2O, we are jointly analyzing observations performed with diverse instruments using radio wavelengths and very long baseline interferometers as well as infra-red data.
