"We investigate the spectroscopic triple system 55 UMa for variations of the elements of the close orbit caused by the tidal interaction with the third component. Based on more than 1300 high-resolution echelle spectra we use the KOREL program to determine the orbital solutions and to disentangle the spectra of the three components. Results confirm the suspected variations of orbital eccentricity and RV-semiamplitude of the close orbit as well as the extraordinary high rate of apsidal advance. From an analysis of the disentangled spectra we determine basic stellar parameters of the three stars." . . . . . "Astronomical Society of the Pacific" .
