  • Aims. The properties of the early-type stars in the core of the Westerlund 2 cluster are examined in order to establish a link bet ween the cluster and the very massive Wolf-Rayet binary WR 20a as well as the Hii complex RCW 49. Methods. Photometric monitoring as well as spectroscopic observations of Westerlund 2 are used to search for light variability and to establish the spectral types of the early-type stars in the c luster core. Results. The first light curves of the eclipsing binary WR… CONTINUE READING
