E. Abstract The influence of angular momentum losses on the evolution of low-mass binary systems with collapsed companions is considered, specifically losses due to magnetically coupled stellar winds, to mass ejection associated with nova explosions, and to gravitational radiation. All evolutionary sequences were found to evolve ultimately to shorter orbital periods since angular momentum losses were effective in outweighing the effects of mass transfer from the less massive to the more massive component. Typical mass transfer rates, induced by the loss of angular momentum associated with magnetically coupled winds, are greater than or approximately equal to 10 to the -9th solar mass/yr. If the empirical braking law for cool main-sequence stars can be applied to the entire lower main sequence, it is found that angular momentum loss via winds dominates gravitational radiation losses in promoting mass transfer in a binary for secondaries greater than or approximately equal to 0.1 solar mass.
