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.

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.

Written specially for practical amateur astronomers who not only want to observe, but want to know and understand the details of exactly what they are looking at. Presents an up-to-date detailed description of the objects, their physics and their evolution (part one); and then (part two) to consider how to observe and record them successfully. Delivers a wealth of information for all levels of amateur observers, from the beginner to the experienced; it is equally fascinating for practical astronomers, and also for those who simply want to find out more about these unusual star systems.

"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.

Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.

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.
