Descripción
An observational test of the binary hypothesis for the origin of the blue straggler (BS) stars has been performed searching for radial velocity variables among 27 BS in five galactic clusters. The significance of the BS phenomenon for the interpretation of evolutionary synthesis models and the spectra of elliptical galaxies is briefly discussed.
