AG Pegasi is a symbiotic star which underwent a nova-like eruption in
the middle of the 18(th) century. As a result of a thermonuclear runaw
ay on the surface of a white dwarf, considerable mass loss from the ho
t component has been observed during the last century. This hot wind i
nteracts with the wind of the red giant(1,2,3). The hot-component lumi
nosity has decreased during the last decade, and on this basis we pred
ict that the colliding-winds stage will end, and accretion from the st
ellar wind will recommence, about the year 2001.
