Scientific paper

Improved orbital elements of the Delta Sge system were determined, using radial velocity measurements. Combined with phase dependent speckle interferometric measurements of the angular separation of the components and with a distance of 100 pc, a mass ratio of 3.5 is obtained. The distance was determined under the assumption that the companion is a main sequence star with effective temperature = 10,500 K (B9) as found from IUE fluxes. A mass loss rate of 0.00000002 M/yr is found for the M2 II primary, using circumstellar FeII absorption lines in the UV spectrum of the B star companion.
