Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.

Download or read book Observing Variable Stars written by David H. Levy and published by Cambridge University Press. This book was released on 1998-04-16 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: David Levy's entertaining, well-researched book is aimed at the amateur enthusiast who likes to learn enjoyably. Beginning with advice on binoculars and telescopes, and how to observe the night sky effectively, the author goes on to describe thoroughly the field of variable star observation, a field in which amateurs have made important contributions. He shows how to interpret variations in light output in terms of the life of a star, from birth through to sometimes violent death. All of the major variable stars are described and classified, as well as other variable objects such as active galaxies, asteroids, comets and the sun. The book also contains a guide to the seasonal night sky. Throughout, practical observations serve to complement the text, producing an exciting, very readable introduction to this fascinating subject.

Available in PDF, EPUB and Kindle. Book excerpt: Founded in 1911, the AAVSO boasts over 1200 members and observers and is the world's largest non-profit organization dedicated to variable star observation. This timely book marks the AAVSO's centennial year, presenting an authoritative and accurate history of this important association. Writing in an engaging and accessible style, the authors move chronologically through five eras of the AAVSO, discussing the evolution of its structure and purpose. Throughout the text, the main focus is on the thousands of individuals whose contributions have made the AAVSO's progress possible. Describing a century of interaction between amateur and professional astronomers, the authors celebrate the collaborative relationships that have existed over the years. As the definitive history of the first hundred years of the AAVSO, this text has broad appeal and will be of interest to amateur and professional astronomers, as well as historians and sociologists of science in general.
Download or read book Variable Stars of Short Period Classic Reprint written by Edward C. Pickering and published by Forgotten Books. This book was released on 2018-02-08 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Variable Stars of Short Period The most natural explanation of the variation of a star of short period is that it is due to its rotation around its axis. In the Annals of the Harvard College Observatory, xi. 264, the variation in light of Iapetus, the outer satellite of Saturn, is discussed on this hypothesis. It is there shown that if the axis of revolution is perpendicular to the line of sight, the variation of light, L, may be approximately represented by the formula, L a 6 sin v c cos 0 d sin 2 v 6 cos 2 v a here denotes the mean light, v the angle of rotation, b and c are constants depending on the comparative brilliancy of the two hemispheres, each of which is supposed to be of uniform intensity, but one brighter than the other; d and a depend on a supposed deviation of the body from the form of a solid of revolu tion. This equation may also be written in the form L a m sin (0 a) 1: sin (2 v B), in which a depends upon the angular position of the plane separating the two hemispheres from the line of sight at the epoch from which the variation in light is reckoned; B in like manner depends upon the positions in which the body subtends its largest and smallest discs. Our problem then is to see how far this equation will represent the variation in light of all the stars of the fourth class.

Book excerpt: A never-before-published masterpiece from science fiction's greatest writer, rediscovered after more than half a century. When Joel Johnston first met Jinny Hamilton, it seemed like a dream come true. And when she finally agreed to marry him, he felt like the luckiest man in the universe. There was just one small problem. He was broke. His only goal in life was to become a composer, and he knew it would take years before he was earning enough to support a family. But Jinny wasn't willing to wait. And when Joel asked her what they were going to do for money, she gave him a most unexpected answer. She told him that her name wasn't really Jinny Hamilton---it was Jinny Conrad, and she was the granddaughter of Richard Conrad, the wealthiest man in the solar system. And now that she was sure that Joel loved her for herself, not for her wealth, she revealed her family's plans for him---he would be groomed for a place in the vast Conrad empire and sire a dynasty to carry on the family business. Most men would have jumped at the opportunity. But Joel Johnston wasn't most men. To Jinny's surprise, and even his own, he turned down her generous offer and then set off on the mother of all benders. And woke up on a colony ship heading out into space, torn between regret over his rash decision and his determination to forget Jinny and make a life for himself among the stars. He was on his way to succeeding when his plans--and the plans of billions of others--were shattered by a cosmic cataclysm so devastating it would take all of humanity's strength and ingenuity just to survive.

Book excerpt: Excerpt from An Introduction to the Study of Variable Stars During the past few years the subject of variable stars has become increasingly interesting to the amateur who is the owner of a telescope, as well as to the average college student who has some knowledge of astronomy, while to the research worker it offers many line of investigation which are full of promise. However, so complex is the subject, and so diverse the principles involved in a complete understanding of it, that extensive reading in several different directions is required as a foundation. It is with the purpose of supplying this need as well as of making an important and attractive branch of astronomy accessible to the student that the present volume has been prepared. It is the outcome of several years of teaching the subject in Vassar College, for which the material was primarily collected. This material is scattered throughout various periodicals in the form either of research papers or quite popular articles, intended to give directions for observation to owners of small telescopes. A large amount of historical matter is also included, which is taken from sources not within easy reach of the general reader. Mention may be made of some of the subjects treated, which are introductory to the study of stellar variation, such as the study of the Durchmusterung charts, photometry in all its branches, spectroscopy, and star color. The purpose of the present volume is to consider all of these points, and in particular to give in as simple and clear a form as possible a full presentation of the physical principles upon which many of the instruments and methods of investigation are based, principles such as those of polarized light, spectrum analysis, the formation of the photographic image, and photo-electricity.

Download or read book Observing Variable Stars written by Gerry A. Good and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
