Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...made in the following manner. The perturbations.of the elements, as originally computed and as given in my papers in the Astronor/zical journal, were first integrated for each date of computation and the resulting perturbations applied to Elements II, thus were formed the osculating elements for each date of computation. With these varying elements the perturbations were computed, using the formulas as given by Oppolzer. The masses of the planets, as adopted, The perturbation of the Mean Longitude was found Lin the form, AL: (AL)1+ (Al.)11 IO. It is of interest to compare the values of the perturbations thus found with those given, for the same interval, by Bauschinger. These latter values were computed by Neugebauer, and Bauschinger's Elements V' were made the basis of the computation. In this work the Osculating Epoch was taken as of I889 October 8.0, Berlin M. T., and the computations were made at a uniform interval of forty days. This brings a date of computation on October 11.0, 1896, for which I " Untersuchungen uber den periodischen Kometen 1889 V, 1896 VI (Brooks)," 2 Theil. " Die Erscheinung 1896-97 und ihre Verbindung mit der vom Jahr date Bauschinger's tables give the integrated values of the perturbations. I could thus take directly from his tables without interpolation the values of the perturbations for the interval between 1889 October 8.0 and 1896 October 11.0. The values of the perturbations as determined by my new computation for this interval can be taken from my tables by interpolation. Interpolating thus and comparing my results with those of Bauschinger, as taken directly from his tables, I find, The differences are all extremely small, with the exception of J/ll. This is accounted...show more
