High Resolution Observations of Masers

Doctoral thesis, 2005

Cosmic masers are associated with both the early and late stages in the life of a star. High resolution observations of maser emissions are unique tools to study the physical and chemical environments in and around young stellar and protostellar objects, and around stars at the end of their life. This thesis consists of high resolution observational studies of cosmic masers associated with both star formation regions using CH3OH masers and evolved stars using SiO Masers. Results of single dish observations of CH3OH masers at high frequiencies are also reported.
