Available in PDF, EPUB and Kindle. Book excerpt: The strong and effective links between amateur and professional astronomers were brought into prominence at Colloquium 98 of the International Astronomical Union. Amateur observations of such objects as comets, variable stars and novae serve to complement work done with expensive instrumentation by professionals. They fill gaps left by big science and often contribute significantly to astronomical knowledge. The book covers: - historical contributions by amateurs, - observational methods, problems and instrumentation, - results of amateur observations, - popularization. Overall, an exciting and enthusiastic account of stargazing, the hobby that can turn into science.

This book was released on 2012-12-06 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This workshop is devoted to Double stars. The general topics of the meeting were: for mation, dynamics and evolutionary tracks. In accordance with the pure tradition of the Saint James way, "pilgrims" from all over the world come to meet together in Santiago. Although with a common interest (double stars), this meeting was a multidisciplinary one, since scientists with different backgrounds participated in it. As a matter of fact, we think that this is the first workshop jointly supported by IAU Commissions 7 (Celestial mechanics) and 26 (Double and multiple stars). It is our belief that this meeting will be the origin of a more close relations and common research. This meeting was held under the invitation of the University of Santiago de Compostela to commemorate its fifth centenary, and organized by the Astronomical Observatory named after its founder, Ramon M. Aller, who made significant contributions in the study of visual double stars, and was one of the pioneers who put the seeds of the present blossoming of Astronomy in Spain. The Scientific Organizing Committee was formed by Drs. C. Allen, P. Couteau, J. A. Docobo, R. Dvorak, A. Elipe, S. Ferraz-Mello (co-chairman), H.A.McAlister, M. Valtonen, C.Worley (chairman) and H. Zinnecker. The Local Organizing Committee was formed by Drs. J. A. Docobo (chairman), A.

Download or read book An Anthology of Visual Double Stars written by Bob Argyle and published by Cambridge University Press. This book was released on 2019-08-29 with total page 968 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern telescopes of even modest aperture can show thousands of double stars. Many are faint and unremarkable but hundreds are worth searching out. Veteran double-star observer Bob Argyle and his co-authors take a close-up look at their selection of 175 of the night sky's most interesting double and multiple stars. The history of each system is laid out from the original discovery to what we know at the present time about the stars. Wide-field finder charts are presented for each system along with plots of the apparent orbits and predicted future positions for the orbital systems. Recent measurements of each system are included which will help you to decide whether they can be seen in your telescope, as well as giving advice on the aperture needed. Double star observers of all levels of experience will treasure the level of detail in this guide to these jewels of the night sky.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes over 300 celestial wonders that can be viewed with common binoculars and low-power "backyard" telescopes incorporating refractors and reflectors. In addition to such showpieces as the Andromeda Galaxy, the largest and brightest of all galaxies after the Milky Way, and the Blue Snowball, one of the autumn sky's outstanding planetary nebulas, over 20 other special objects are listed and characterized, many of which are visible to the unaided eye on a dark, clear night. The sun, moon, Venus, Mars, Jupiter, Saturn, and other members of the earth’s solar system are also described, as are such bright asteroids as Ceres, Juno, and Vesta; open star clusters, diffuse nebulas, supernova remnants, spiral galaxies, elliptical galaxies, and a host of other astronomical phenomena. An abbreviated descriptive format is used to accommodate as much information on observation as possible for both field and armchair use.

Available in PDF, EPUB and Kindle. Book excerpt: Double and multiple stars are the rule in the stellar population, and single stars the minority, as the abundance of binary systems in the space surrounding the sun shows beyond doubt. Numerous stellar features, and methods of their exploration, ensue specifically from the one but widespread property, the binary nature. Stellar masses are basic quantities for the theory of stellar structure and evolution, and they are ob tained from binary-star orbits where they depend on the cube of observed parameters; this fact illustrates the significance of orbits as well as the accuracy requirements. Useful in dating stellar history is the knowledge that components of a system, different though they may appear, are of the same origin and age. Between star formation and the genesis of binaries a direct connection can be traced. The later stages of stellar life branch into a great variety as mutual influence between the components of a close binary pair develops. Transfer and exchange of mass and the presence of angular momentum in the orbit give rise to special tracks of evolution, not found for single stars, and to peculiar spectral groups. This is not a new story but it has a new ending: The patterns of evolution involving mass transfer appear to lead ultimately to single objects.
