Scientific paper

Radial-velocity observations of the binary SS Ari were carried out in the last quarter of 1990 and on the first clear night of 1991 at the Dominion Astrophysical Observatory. A spectroscopic orbit was determined on the assumption that both components of the binary are undistorted and revolve in circular orbits. It is shown that SS Ari belongs to the W subclass of the W UMa systems and has properties that are typical of that subclass.
