Scientific paper

Photometric and spectroscopic observations of V701 Cen have been analysed. It is found that V791 Cen is a triple system comprising an eclipsing pair which is a semi-detached system plus a third component. The authors obtained an A0 V spectral type for the primary component of the eclipsing pair and A3 V-IV, A0 - A2 V-IV for the secondary and third component respectively. Chromospheric activity might be present in one of the components of the eclipsing pair. Sudden jumps in the radial velocities are suggested to be due to the presence of a gaseous stream in the system.
