Download or read book Discovering Double Stars written by Agnes Clarke and published by . This book was released on 2021-08-09 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discovering Double Stars helps you to find and learn about 300 of the best double stars visible to Northern Hemisphere observers. This book is specifically for those living in the glare of urban sprawls, where all but the brightest stars are lost to light pollution. Overview charts tailored to light polluted skies show the general position of the doubles, while generously proportioned detail charts show the precise star patterns around the doubles themselves, enabling an observer to locate the stars through a finder scope. Cross-references to the SAO, HIP and Gaia DR2 catalogs are provided for the doubles.
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 1000 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: "Observing Visual Double Stars, " written by an astronomer who has discovered almost 2,000 of them, opens the way to amateur astronomers who wish to make a direct and real contribution to science through their avocation.Double or binary stars--pairs of stars that revolve around one another--were once thought to be rare, anomalies among the vast number of normal, isolated stars, like our sun. Now, however, it is believed that many if not "most" stars are mated in binary systems. The visual binaries are those whose component stars are rather distant from each other and require decades or even centuries to complete their orbits. Few professional astronomers devote their time to making the observations needed, over these extended periods, to determine the characteristics of even a small sample of these systems. Thus, if any sizable number of double stars are to be closely scrutinized, their periodic variations plotted, and their orbits and masses calculated, the host of amateur astronomers will have to come to the aid of the professionals by making patient, systematic, night-after-night, year-after-year recorded observations."Observing Visual Double Stars" is designed to train amateurs to become such lookouts. After a historical account of the discovery of binaries (from the sighting of the first in 1650, through the work of the Herschels and the Struves in the eighteenth and nineteenth centuries, to the present), the author describes the various classes of telescopes and other instruments and the relevant optical principles. This is followed by practical advice on how to use this apparatus to identify double stars and measure their variations over time.The heart of the book--and its technically most advanced section--presents the mathematical techniques that will allow the observer to calculate orbits and masses from the variables that have been measured. A chapter entitled "Voyage to the Country of Double Stars" describes a binary system as it might appear to an observer within it. The book also explains the use of star catalogues and presents its own catalogue of 744 double stars accessible to the amateur observer.
Download or read book Discover the Stars written by Richard Berry and published by Crown. This book was released on 1987-12-13 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accessible, informative guide to identifying constellations and other incredible features of the sky, whether you’re hiking, camping, or stargazing from your backyard. Discover the Stars leads you on a tour of all the stars and constellations visible with the naked eye and introduces you to deep-sky objects that can be seen with binoculars or a simple telescope. The tour is conducted by the editor of Astronomy magazine, Richard Berry, whose two-color, computer-plotted sky maps and clear instructions make stargazing fun and productive from your first night out. The heart of Discover the Stars is two sections of big, beautiful sky maps and charts. The first section features twelve maps that show the entire sky overhead as it appears during each month of the year. These outline all the constellations visible anywhere in the Northern Hemisphere, and the accompanying text reveals the rich ancient mythology that surrounds the star groups. The second section is made up of twenty-three star charts that depict smaller regions of the sky in great detail. These charts give the names of key stars and lead you to fascinating features such as stars with unusual colors, double stars, variable stars, nebulae, and galaxies. Separate chapters cover basics, such as how the stars move through the sky, how to find your way around the moon and the planets, making an astronomer's flashlight, and choosing and using a telescope—all in terms that are easy to grasp and remember. Discover the Stars is the perfect introduction to the heavens, simple enough to be useful if you're just starting out but packed with enough information to keep you learning and enjoying the stars for years to come.

Book excerpt: "A short, excellent account of [Leavitt’s] extraordinary life and achievements." —Simon Singh, New York Times Book Review George Johnson brings to life Henrietta Swan Leavitt, who found the key to the vastness of the universe—in the form of a “yardstick” suitable for measuring it. Unknown in our day, Leavitt was no more recognized in her own: despite her enormous achievement, she was employed by the Harvard Observatory as a mere number-cruncher, at a wage not dissimilar from that of workers in the nearby textile mills. Miss Leavitt’s Stars uncovers her neglected history.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A General Catalogue of 1920 Double Stars: Discovered From 1871 to 1899 A general catalogue of all the double stars discovered by me from time to time during the past twenty-hye 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 become 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, astronomical periodicals, etc. It is difficult, 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.
