Close binary systems of the RS CVn and Algol type are characterized by a highly variable radio emission, from typical flux densities of a few mJy during low-activity (quiescent) periods, up to 1 Jy during strong flares. The origin of this radio emission is attributed to the gyrosynchrotron mechanism. Several observations of these stars have shown an evolution of the radio spectrum during both the rising and decay phases of flares. ...

Asymptotic Giant Blanch (AGB) Stars: For low and intermediate-mass stars (with initial masses between about 0.8 to 8 solar masses) the most important nucleosynthesis occurs when stars evolve off the main sequence to the giant branches. ... This indicates that these stars obtained their unusual abundances via mass transfer from a previous red giant star, that has long evolved away. ...
