The Henize sample of S stars
A collaboration between the Bruxelles and Geneva groups
The aim of the thesis was to clarify evolutionary links between several peculiar red giant stars families, mainly barium stars and S stars. In particular, the Henize sample of 205 S stars (Henize, 1960) has been studied in order to infer statistical properties of S stars (binarity, mass, luminosity, photometric variability, spectroscopic features, infra-red excess, technetium abundance, galactic distribution, symbiotic properties).
