Spectroscopic characterization of the known O-star population in Cygnus OB2. Evidence of multiple star-forming bursts
Context. Cygnus OB2 provides a unique insight into the high-mass stellar content in one of the largest groups of young massive stars in our Galaxy. Although several studies of its massive population have been carried out over the last decades, an extensive spectroscopic study of the whole known O-star population in the association is still lacking
