Scientific paper

The dynamical evolution of stellar winds and planetary nebulae in elliptical galaxies is studied. The ionizing photon density as a function of galactic radius is estimated, and the evolution of ionized and partially neutral stellar ejecta is described. The evolution of supernova bubbles is addressed, and the dynamics and local metal enrichment of individual bubbles are described, approximating the stellar remnant as an 'inertial piston'. The total metal enrichment and other global properties of the ensemble of bubbles within an elliptical galaxy is discussed.
