Resumen:
We present the first results of an observational project titled "The stellar multiplicity in the dynamics of stellar clusters", that is aimed at the study of stellar multiplicity in poor open clusters dominated by one or a few massive central stars. The main goal is to determine the role of massive multiple systems in the dynamical evolution and the eventual disintegration of the clusters. In this work we present the results of the spectroscopic observations carried out during the first semester of 2018 in the Complejo Astronómico El Leoncito (CASLEO), where we obtained spectra of 155 stars belonging to 15 stellar clusters. The target selection was made taking into account an astrometric study of membership previously made using the GAIA catalog. The spectroscopic observations are used to measure radial velocities and perform a variability study to detect binary or multiple systems.
