Perturbations. Current Photographic Studiesal magnitude, spectrum, parallax as well as the period of revolution ., eccentricity . of the perturbation orbit and the adopted value for the mass . of the unseen companion (Chapter 11, formulae (11.17ff)). Only for two stars, Ross 614 and VW Cephei the companion has been seen later (Chapter 14).

Verletzlichkeiten und versteckte Ängsteproportional to the masses of the respective components. On a background of reference stars, the binary components move in non-rectilinear paths, which are the resultant of the uniform rectilinear motion of the center of mass and the orbital motion of the individual components.

It is one more proof of the reliability of the law of gravitation that paths, past and future, of the planets can thus be predicted more precisely than when the perturbations are neglected.
