The Detection of Triple Systems Through the Precession of the Nodes Effect

摘要: This paper is a report on new technique for detecting close triple stars and current observational project with some preliminary results, using this method. The goal of the to discover systems where ratio between long short orbital period small. A system will be called if its several days. In most known (Fekel 1981), very large. can attributed fact that wide orbit has been detected visually in cases. few exceptions (e.g. λ Tau, Ebbighausen Struve 1956), was discovered by additional periodicity derived velocity pair mass center γ As small modulation imposed large radial variation associated pair, many could have escaped kind detection. Consequently, present typical or averaged might highly overestimated.
