Scientific paper

By means of spectrographic observations obtained at CTIO, Chile, the authors have determined that HDE 320102 is an O6+WN binary system, with an orbital period of 12.595 days. The authors present an analysis of the orbital elements of this system based on radial velocities of the absorption lines of the O6 component, and of the He II λ4686 and N V λλ4603-19 emissions of the WN component.
