Studying the Influence of the Local Environment in the Formation of Star Clusters

We will discuss some of the results of our comparative study of of young star clusters in several galactic molecular complexes. By combining data in various wavelengths (IR, X-rays, Radio) we attempt to unlock the star forming properties of clusters forming in diverse environments. Our goal is to understand those properties in the context of a) the presence or even the absence of massive stars, and b) the primordial structure of the cloud. We will put into consideration the possibility that the primordial structure of the clouds may play a role as significant or more significant than triggering processes. Young star clusters form in dense gas clumps that dissipate rapidly, in timescales comparable or shorter than the dissipation timescales of circumstelar disks in the young stars. By studying the spatial distribution of class by evolutive classes and by comparing the brightness distributions of clusters with evolutive models, we are able to trace the histories of star formation of the complexes, leading to a better understanding of the process by which the galactic disk is being populated.
