Available in PDF, EPUB and Kindle. Book excerpt: Part of the exclusive new CAEZIK Notable line of books. Many of Heinlein's fans consider the novels he wrote in the fifties amongst the author's strongest work; when he was at the peak of his talents. Double Star is considered by many to be the finest of his titles. Brian Aldiss called it his "most enjoyable novel." Whether it is the simplicity of a lively tale, the complexity of the situation, or the depth of characterization, the book has developed a loyal following. It also won Heinlein his first Hugo. The story revolves around Lawrence Smith--also known as "Lorenzo the Great"--a down-and-out actor wasting the remainder of his life in bars. When he encounters a space-pilot who offers him a drink, before he knows what is going on, he is on Mars involved in a deep conspiracy with global consequences. He is given a mission where failure would not only mean his own death, it would almost certainly mean an all-out planetary war. "Heinlein's novels of the 1940s and 50s shaped every single science fiction writer of my generation and everyone currently writing science fiction. Or making science fiction movies ... and Double Star is an excellent example of all the reasons why."--Connie Willis CAEZIK Notables is a new line of science fiction and fantasy titles that have had a significant impact on their respective genre. Each book has a unique place in the development of speculative fiction. Every title published under the CAEZIK notables line will have a matching cover set and will carry an introduction by an expert in the field.

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 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.

Download or read book Making Stars Physical written by Stephen Case and published by University of Pittsburgh Press. This book was released on 2018-11-03 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Making Stars Physical offers the first extensive look at the astronomical career of John Herschel, son of William Herschel and one of the leading scientific figures in Britain throughout much of the nineteenth century. Herschel’s astronomical career is usually relegated to a continuation of his father, William’s, sweeps for nebulae. However, as Stephen Case argues, John Herschel was pivotal in establishing the sidereal revolution his father had begun: a shift of attention from the planetary system to the study of nebulous regions in the heavens and speculations on the nature of the Milky Way and the sun’s position within it. Through John Herschel’s astronomical career—in particular his work on constellation reform, double stars, and variable stars—the study of stellar objects became part of mainstream astronomy. He leveraged his mathematical expertise and his position within the scientific community to make sidereal astronomy accessible even to casual observers, allowing amateurs to make useful observations that could contribute to theories on the nature of stars. With this book, Case shows how Herschel’s work made the stars physical and laid the foundations for modern astrophysics.

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.

Download or read book Observing and Measuring Visual Double Stars written by R. W. Argyle and published by Springer Science & Business Media. This book was released on 2012-09-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Observing and Measuring Visual Double Stars (2004) is the definitive book for those who are serious about this fascinating aspect of astronomy. It deals with equipment (you can start modestly with commercial or even home-made instruments), observing methods using binoculars upwards to advanced instrumentation and techniques, including speckle interferometry. The astronomy of double stars, including orbital calculation, is given its own section. This second edition of this popular book contains a significant amount of completely new material, inspired by the work done by observers – particularly in the USA – since the first edition was published. This includes the use of the Internet to carry out astrometry (precise astronomical measurement) using existing survey plates and films. The new edition contains an excellent guide to sketching double stars, a topic not previously covered. In addition, there is information about how to image double stars of unequal brightness, always a difficult matter but now somewhat easier because of advances in hardware and image-processing software. Nearly all of the chapters and tables have been updated. The CD-ROM that accompanied the first edition of Observing and Measuring Visual Double Stars is replaced by access to the Springer Extras web site. The extra information includes the complete Washington Double Star and Tycho-2 Catalogs. There is an extensive database of astrometric, double-and multiple-star formation, including positions, orbits, separations, and magnitudes, and a software suite that implements many of the calculations and equations featured in the book.

Download or read book Double Stars written by W.D. Heintz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 185 pages. 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.

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.
