000002849 520__ $$aWe report on our radial velocity monitoring project of a wide range of evolved stars where binarity was proposed to explain some of their peculiarities. Our spectrograph HERMES is a new optical echelle spectrograph mounted on the 1.2m Mercator telescope on La Palma, built by a consortium of Belgian Institutes (KULeuven, ULB, Royal Observatory) with contributions from the Geneva Observatory and Landessternwarte Tautenburg. By combining high S/N single observations with low S/N time-series, we aim at quantifying the orbital and chemical characteristics of every distinct subgroup. The final goal is to gain insight in the diverse binary interaction processes relevant at late stages of stellar evolution. We discuss our project, the unique capabilities of HERMES, and present the first results of our program.
