Water masers associated with two carbon stars: EU Andromedae and V778 Cygni
We observed the 22.2 GHz H2O maser line from the two C stars EU And and V778 Cyg. The intensity of the line has varied by more than a factor of 5 over several month and the line has shown additional weaker components. We interpret the system as being binary with a C and an M star component with a thick shell.
