Rotationally-perturbed orbital elements of close binary systems
The aim of this investigation is to present the secular and periodic perturbations of the six orbital elements of a close binary system due to rotational distortion. In our study we consider very small inclinations of the orbital plane of the system, whereas the eccentricity of the orbit may assume any value between \(0<e<1\). The final formulae for the various elements have been expressed by means of the unperturbed true anomaly measured from the ascending node.
