Proper Motions of Water Masers in Circumstellar Shells
Published online by Cambridge University Press: 12 April 2016
Abstract
We present measurements of proper motions for circumstellar water maser observations obtained with the VLBA. Results of the observations and modeling indicate that the water masers exist in a kinematically complex region of the circumstellar envelope. A change in position of the maser spots as a function of velocity is discussed.
