Description
The formation and early evolution of high-mass stars happens in
clustered and highly complex environments, where the forming stars
and the molecular cloud are mutually interacting. To study the stellar
population of high-mass star-forming regions, we have started a program
aiming at a spectroscopic classification of all the high- and
intermediate mass cluster members of a well selected sample of 10 galactic young clusters as well as to study the interaction between the stars and
their environment.
I will present the first results of this survey obtained with the
integral field spectrograph SINFONI at the VLT. Supporting
multi-wavelength data (mid-infrared, sub-mm and radio) are added to
obtain a complete picture of the regions. The first results show that
properties like distance and ages of the clusters can be derived.
Additionally, the multi-wavelength datasets of the regions and their
environment result in a detailed assessment of the formation history
of the targeted regions and shows that multiple generations of star formation are present in every cluster.
