Abstract

 

We have been monitoring the water maser emission from the circumstellar shells of 11 variable stars and comparing the variation in maser emission to the visible light curves. Two of these stars (V778 Cyg and EU And) in which we have detected maser emissions are carbon stars which are not expected to have water in their circumstellar material. We encourage AAVSO observers to observe these unusual carbon stars.
