This book was released on 2017-02-03 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Measures of Double Stars With the 40-Inch Refractor of the Yerkes Observatory in 1900 and 1901 The double-star measures recorded here were made principally in the years 1900 and 1901. The observations preceding this period were almost entirely of the B stars; and the mean results have been incorporated in the General Catalogue of 1290 Double Stars discovered by the writer from 1871 to 1899, and issued in 1900 as Vol. I of the Publications of the Yerkes Observatory. The detailed measures have not been printed, but, as the results have been given in connection with all the measures of these stars, arranged In chronological order, I have not thought it worth while to give the separate observations. In making the working-list of objects for measurement, the purpose was to include no star likely to be observed elsewhere, and to confine it wholly to long-neglected and little-known pairs, and those which for the lack of sufficient measures, or the uncertainty of the early results, could not be classified as to motion or otherwise. These stars, so far as the early astronomers are concerned, come largely from the several catalogues of the two Herschels and South, with some of the rejected Struve pairs also catalogued and roughly measured by Herschel II. Many of these, and particularly those from Herschel I. And South, are wide pairs, and too widely separated to be considered by modern observers as double stars in the proper sense of the term; and, whenever change has been found in this class of objects, it is very probable that it is due to the proper motion of one or the other of the components. In the other class, where the distances are less, the changes, if confirmed by later observations, may point to physical systems, though, of course, the orbital movement would of necessity be slow. It seemed very desirable that these stars, among the oldest known so far as the literature of the subject is concerned, and observed by the most eminent astronomers who have ever lived, should receive sufficient attention from modern observers to show whether or not In this long interval there has been any relative motion. In many instances the measures now made do not satisfactorily determine this, since the apparent change may be accounted for by errors in the single observations made when the pair was first catalogued, and another series of measures at some later time may be necessary.

Book excerpt: Excerpt from A General Catalogue of 1290 Double Stars Discovered From 1871 to 1899 by S. W. Burnham: Arranged in Order of Right Ascension With All the Micrometrical Measures of Each Pair A general catalogue of all the double stars discovered by me from time to time during the past twenty-hwe years has long been needed by those interested in this field of astronomical research. And, by reason of the special interest attached to many of these remote sidereal systems. It has'becomc more and more important to bring the scattered material together in order to intelligently pursue the investigations which promise to so much increase our knowledge of the great universe beyond the solar system. These discoveries are scattered through nineteen different catalogues. Published at various times and places, commencing with 1873; and the observation of these stars by a great num ber of astronomers in this country and in Europe can only be made use of by consulting hundreds of volumes of observatory and society publications. Astronomisal periodicals. Etc. I t is difl'icult. If not practically impossible. For the general observer or investigator to make a really complete collee tion of all the measures of a large number of these stars, Many of the observations are in obscure and unusual places. And in works not always readily accessible. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book A General Catalogue of Double Stars Within 121 of the North Pole Vol 1 Classic Reprint written by Sherburne Wesley Burnham and published by Forgotten Books. This book was released on 2017-11-12 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A General Catalogue of Double Stars Within 121° of the North Pole, Vol. 1 There is another class of double stars, principally from the observations of comparatively modern observers, where no attempt seems to have been made, beyond perhaps reading the coarse circles of the equatorial, to identify the star or give the exact place. As many as possible of these stars have been identified; others are not in or very near the given places; and still others obviously have large and uncertain errors of place which will make their identification hereafter a matter of accident or good luck. There seemed to be no object to be gained by giving the right ascensions any closer than the nearest whole second of time, since as a matter of fact a large number of these stars have a much greater uncertainty in place from the lack of meridian positions, and from the lack of knowledge of their proper motions; and to give the right ascensions to small fractions of a second would imply an accuracy which would be unwarranted by the material at hand. This is also true generally of the decli nations. While perhaps for a greater part of the stars, the nearest tenth of a minute of arc might have been given, it would have had no significance in the case of several thousand stars; and in any event would not have made the catalogue any more useful for any conceivable purpose, practical or otherwise. In any investigation concerning the proper motion, or the exact place of the star, the original catalogues of position will of course be consulted. All of the stars are north of the equator, unless otherwise indicated by the minus sign attached to the degrees of declination. The advantage of the omission of the plus sign for the northern stars in rapidly finding any star, either north or south, will be apparent to those who have had to do this frequently in catalogues where all the signs are given.
