The evolution of a binary system consisting of a 1-solar-mass main-sequence star and a 5-solar-mass evolved red giant in a common envelope is investigated. A wide orbit is assumed, and processes leading to the formation of the common envelope are discussed. Both tidal and frictional angular-momentum transfer between the internal binary and the envelope are taken into account. The evolution is found to result in rapid shrinkage of the internal binary in an extended envelope of nearly constant high luminosity. It is concluded that the common-envelope evolution of a main-sequence star with a degenerate core will normally reduce an initial wide separation to distances of a few solar radii in less than 1000 yr.
