Jf. Ling et al., THE STROBOSCOPIC METHOD APPLIED TO THE STELLAR 3-BODY PROBLEM - THE KEPLERIAN OUTER ORBIT APPROXIMATION, The Astronomical journal, 110(2), 1995, pp. 875-879
This article discusses the stellar three-body problem using an approxi
mation in which the outer orbit is assumed to be Keplerian. The equati
ons of motion are integrated by the stroboscopic method, i.e., basical
ly at successive periods of a rapidly changing variable (the eccentric
anomaly of the inner orbit). The theory is applied to the triple-star
system xi Ursae Majoris. (C) 1995 American Institute of Physics.
