Despite a significant fraction of stars form in stellar clusters counting hundreds to thousands of members, almost all the stars we observe today in the Milky Way is not associated to any stellar cluster. This occurs because newborn stellar clusters are typically dispersed in a few million of years by several intervening processes, such as the gravitational interaction among cluster
LSST (Large Synoptic Survey Telescope) is the future of the astronomy in the time domain. LSST is a new-generation telescope that will be built on Cerro Pachon in Chile (2700 meters). It will be equipped with a primary mirror of 8.4 meters of diameter and an innovative camera able to observe an very large field of view, more than 49
In the Milky Way one of the main modes of star formation is in stellar clusters, which remain associated with their parental cloud for about 5-10 million years. This makes the star forming regions complex targets, characterised by rich stellar populations packed into small regions, sometime even with massive stars, and clouds whose morphology and properties are affected by the
