The Importance of Wide-System Studies for Stellar Evolution and Galactic Dynamics,e visual pairs (short periods) may lead to mass-determinations in a relatively short time interval. But mass-determination should not be considered as the only interest of double star astronomy, even if it is of a fundamental nature..Today, it appears that researches on the origin and the evolution

Symbiotic Stars, available on the spectral variations at optical wavelengths these stars undergo. I do not give extensive references to those data, for previous reviews have done so quite adequately. Rather, I concentrate on the extensive widening of the wavebands within which symbiotic stars have been studied over

,Radial Velocity and Profile Variations of the Ultraviolet Circumstellar Lines in ζ Tauri,l atoms, and once or twice-ionized ions (except CII, Al III, Si III resonance lines) follow the same velocity variations as in the visual spectra, while the Si IV and C IV resonance lines show a constant negative velocity (～ —50 km s. at the core). The Al III, C II resonance lines and probably Fe II
