Book excerpt: Excerpt from Measures of Proper Motion Stars Made With the 40-Inch Refractor of the Yerkes Observatory in the Years 1907 to 1912 The other list, forming Part I, includes all other stars for which prior observations with the micrometer have been made. Unfortunately the early work in this field is confined to a few observers, the principal ones being Otto Struve, Engelhardt, and Ball. For some of the other stars recent photographic positions have been found, but in most cases the time-interval is too short to give a very accurate value of the relative change. This objection will be removed by observations to be made hereafter. The small stars from Zone 26 of the Oxford Astrographic Catalogue are taken from a list prepared by Mr. G. H. Hamilton of the University Observatory. This list gives the place, proper motion, and photographic magnitude of some fifty stars, principally below the magni tude limit in Argelander, from plates taken for the most part in 1907 and 1908, the proper motions being derived from a comparison with other plates made a few years earlier. All of these were put on the observing-list and, as far as possible, compared with one or more fainter stars in the field. In a few instances there were no comparison stars within the range of the micrometer. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Deep Fields written by S. Cristiani and published by Springer Science & Business Media. This book was released on 2001-12 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a synopsis of modern deep-field astronomy, based on the powerful telescopes and instruments developed in recent years. It is organized along topical themes, such as the extragalactic background radiation at different wavelengths, the evolution of galaxies, the history of star formation, the nature of absorbers, the reionization of the intergalactic medium, the validity of photometric redshifts, gravitational lensing, and clustering of galaxies. Stellar and substellar objects were not neglected, however, and one session was devoted to nearby bodies such as trans-Neptunian solar system objects, brown dwarfs, and stars with special characteristics.

This book was released on 2012-12-06 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: H.T. MacGilLIVRAY Royal Observatory Blackford Hill Edinburgh EH9 3HJ Scotland U.K. lAU Symposium No. 161 on 'Astronomy from Wide-Field Imaging', held in Potsdam, Germany, during 23-27th August 1993, was the first conference organised by the recently-formed Working Group of lAU Commission 9 on 'Wide-Field Imaging'. This Working Group was instigated during the XXIst meeting of the General Assembly of the International Astronomical Union in Buenos Aires in 1991, and represented a merging of the former formal lAU Working Group on 'Astronomical Photography' and the informal 'Digitised Optical Sky Surveys' Working Group. Dr. Richard West was 'invited' to be Chairperson, and hence was given the daunting task of organising the Group from scratch. The very fact that the first conference after only two years was a major lAU Symposium says much about the determination and enthusiasm of Richard West to fulfilling the aims of the new Working Group. The siting of the conference in Potsdam in formerly East Germany provided an excellent opportunity to advantage from the political changes in Eastern Europe. Good access to the meeting was possible by scientists from Eastern European countries, allowing exchange of information on the very important Wide-Field facilities in both East and West, information on the rich archives of photographic plates that exist in both East and West, and allowing discussions between scientists facing very similar problems in both East and West.
