Scientific paper

The computations of D'Antona and Mazzitelli (1982), together with the evolutionary scheme of cataclysmic binaries (CBs), imply that the secondaries in those CBs which have periods shorter than about 4.5 hr also possess a large He-3 envelope content, when the nova systems in question are several billion years old. Attention is presently given to the consequences of these considerations for the frequency of novae outbursts. It is predicted that in cases where Li is produced by galactic novae, the Li-7 content of old disk stars should approximate that of the Population II content.
