Spencer, J. H. ; Johnston, K. J. ; Moran, J. M. ; Reid, M. J. ; Walker, R. C. Abstract The H2O maser emission features for each of the stars, RT Vir, W Hya, RX Boo, and RR Aql, have been found to lie in a region of no more than about 10 to the 14th cm. The masers are probably located in a shell surrounding the star. There have been order-of-magnitude variations in the flux densities of these H2O masers since 1973, and variations in the infrared flux of these stars should have been expected if the masers are pumped by IR photons. Weak, broad, quasi-thermal features are found to underlie the narrow features in W Hya, RX Boo, and R Aql.
