BLUE STRAGGLERS AS A MERGING PRODUCT OF LOW-MASSIVE MAIN SEQUENCE BINARIES WITH DETACHED COMPONENTS

Анотація


In the framework of magnetic braking formalism the evolutionary chain describing the sequential evolutionary transitions of the low-massive detached close binaries into "short- periodic" RS CVn-type systems and then into W UMa-class contact stars with the final stage of the single objects of Blue Stragglers-type was reconstructed. This problem was solved with the use of extensive observation materials. The relations of statistics and lifetimes obtained for systems participating in evolutionary chain serve as an evidence for genetic relationship of given objects.
