Scientific paper

The central parsec of our Galaxy harbors a cluster of young massive stars orbiting the supermassive black hole SgrAstar. We present a detailed analysis of these stars, focusing on their stellar and wind properties. We show that they are similar to other Galactic stars, pointing to no particularly special evolution in spite of the hostile environment. We are able to identify a clear evolutionary sequence between Ofpe/WN9, WN8, WN/C and LBV stars. The population of Wolf-Rayet and OB stars fully accounts for the ionizing radiation necessary to produce the observed nebular emission.
