Context. Interferometry can provide spatially resolved observations of massive star binary systems and their colliding winds, which thus far have been studied mostly by means of spatially unresolved observations. Aims. In this work, we present the first AMBER/VLTI observations, taken at orbital phase 0.32, of the Wolf-Rayet and O (WR+O) star binary system γ Velorum and use the interferometric observables to constrain its properties. Methods. The AMBER/VLTI instrument was used with the… CONTINUE READING
