Scientific paper

The authors study the evolution of binaries in which a low-mass giant with a helium or carbon-oxygen core is transferring matter to a more massive compact companion. In the case of the He-core giants mass transfer rates of ≡10-6 - 10-7M_sun;/yr are found, which persist for ≡106yr, while for the CO-core giants the corresponding values are ≡10-6M_sun;/yr and ≡105yr respectively. The stellar wind from the giant may play an important role in the evolution of these binaries. When the compact companion to the giant is a white dwarf the systems modeled might be observed as symbiotic stars.
