Abstract

We study the mass loss phenomenon which is though to be generally seen in the evolution of late type stars. We are using radio interferometry European VLBI Network (EVN) and Multi-Element Radio Lined Network (MERLIN) to study maser emission from gas molecules of H2O and OH. This enable us to obtain 10-30 mas resolution images of mass-loss in AGB stars
