A classical nova model is evolved through a complete cycle, including accretion leading to outburst, mass loss, accretion again, ending in another outburst. Mass loss is found to occur in three different stages: shock ejection, continuous mass loss through an optically thick wind, and concentration of the central star, leaving behind a thin, slowly expanding nebula. There is a striking correspondence between the evolution of the model and the observed development of the nova spectrum. The entire accreted mass is ejected, as well as a small amount of the underlying WD material. The composition of the ejecta is very similar to that obverved in nova shells, with a similar estimated Z. A remnant helium-rich envelope of small mass is left on the WD. 52 references.
