Star clusters in the VVV survey

Young massive stellar clusters (age < 10Myr, M~1.000-10.000 solar masses) are good laboratories to observe massive stars and test stellar evolution theories. Because these clusters are very young, we need near infrared data to access their stellar population. In this talk we will present the massive clusters investigates by our group using the ESO public survey Vista Variables in the Via Lactea (VVV). Our cluster database includes new clusters with spectroscopically confirmed OB-stars, massive young stellar objects, Wolf-Rayet, variable stars. This database allows to homogeneously derive a cluster physical characterization and, with them, we can begin to explore relations between the cluster stellar population, their intrinsic parameters and the Milky Way (distance to the Galactic center or spiral arm structure, for example).
