A Modification of the Perturbations-of-Elements Method.

Series: Monthly Notices of the Royal Astronomical Society, vol. 109, no. 4, 1949; Communications from the University Observatory, Oxford, no. 27. 9.75 inches. pp. 21-35, [1]. Blue printed wrappers. Very good. Abstract: The division of the orbit of a comet or minor planet, into an integral number of parts, permits the construction of special tables which facilitate the calculation of the special perturbations, by the planets, in terms of the variations of the usual ecliptic elements. Such tables have been published, but the approximate methods usually employed with them are not, it is argued, accurate enough to be generally suitable for the predictions of the returns of periodic comets. A rigorous method, treating the time element as perturbed and the mean anomaly as the independent variable, is here derived, very simply, for use with these tables or with the new ones proposed. And the integration of the perturbations of the mean anomaly, involving a double integration, is replaced by a single integration of the perturbed time interval.
