Abstract
Matter of solar system composition has been added to the surfaces of two initially cool carbon-oxygen (CO) white dwarfs of masses 0.5 M☉ and 0.8 M☉ at rates in the range 10-8 to 10-6 M☉ yr-1. Four different regimes are encountered. (1) At the highest accretion rates, models become red giants after the accretion of only a very small amount of mass. As the accretion rate is decreased, models are encountered that (2) burn hydrogen at the same rate at which it is accreted, (3) experience a series of nondynamical hydrogen shell flashes followed eventually by a powerful helium shell flash, and, finally, (4) experience nova-like hydrogen shell flashes.
