Der Einfluß des SCHWARZSCHILD-Effektes auf die Bahn-und Systemelemente lichtschwacher und kurzperiodischer spektroskopischer Doppelsternsysteme

The influence of the SCHWARZSCHILD effect on the orbital and system elements of weak and short-periodic spectroscopic binaries has been examined. It effects the observational times and phases by broadening the spectral lines. Analyzing two model system – a theoretical one and a real weak and short-periodic binary (BD + 57° 1942) – correction terms have been determined and their influence on the orbital and system elements by a method of WILSING and RUSSELL have been studied.
