摘要：

We present an ISO LWS 43-197 mu m grating spectrum of the oxygen-rich AGE star R Gas. The spectrum is rich of isolated and blended H2O lines. For their identification and in order to determine the physical parameters of the circumstellar envelope, we have constructed a model which treats radiative transfer, chemical exchange and photodissociation reactions, and various heating and cooling processes in a consistent manner. By fitting the observed line fluxes and using stellar parameters based upon the Hipparcos distance, we derived a mass-loss rate of (M) over dot = 1 10(-6) M. yr(-1) which is close to the value 6 10(-7) M. yr(-1) previously derived for W Hya, another oxygen-rich AGE star.
