Download or read book Understanding Variable Stars written by John R. Percy and published by Cambridge University Press. This book was released on 2007-05-24 with total page 330 pages. 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.

Book excerpt: The unfinished sci-fi masterpiece by the author of Stranger in a Strange Land—completed by the Hugo Award–winning author of The Stardance Trilogy. Joel Johnston has found the love of his life in Jinny Hamilton. Life would be perfect if only he earned enough money to support a family. But now that Jinny knows his love is true, she reveals an incredible secret: she is really Jinny Conrad, granddaughter of Richard Conrad, the wealthiest man in the solar system. And now that Joel proven his love for Jinny, her family has a plan for him. Joel is to be groomed for a place in the vast Conrad empire and sire a dynasty to carry on the family business. Most men would jump at the opportunity. But to Jinny’s surprise, and even his own, Joel turns down her generous offer and sets off on the mother of all benders. When he wakes up on a colony ship heading into space, he decides it’s time to forget Jinny and make a life among the stars. But his plans—and the plans of billions of others—are shattered by a cosmic cataclysm so devastating it will take all of humanity’s strength and ingenuity just to survive. When an outline for Variable Star was found among Robert A. Heinlein’s papers, Spider Robinson was commissioned to complete the novel. The result is a thrilling new work of science fiction from two of the genre’s greatest minds.
Download or read book Observing Variable Stars written by Gerry A. Good and published by Springer Science & Business Media. This book was released on 2003 with total page 290 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.

Download or read book Pulsating Stars written by Márcio Catelan and published by John Wiley & Sons. This book was released on 2015-03-23 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys our understanding of stars which change in brightness because they pulsate. Pulsating variable stars are keys to distance scales inside and beyond the Milky Way galaxy. They test our understanding not only of stellar pulsation theory but also of stellar structure and evolution theory. Moreover, pulsating stars are important probes of the formation and evolution of our own and neighboring galaxies. Our understanding of pulsating stars has greatly increased in recent years as large-scale surveys of pulsating stars in the Milky Way and other Local Group galaxies have provided a wealth of new observations and as space-based instruments have studied particular pulsating stars in unprecedented detail.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains everything you need to know about variable stars -- stars whose brightness varies noticeably over time. The study of variable stars has been a particularly popular area of research for amateurs for many years; the material contained herein serves as both an introduction to amateur astronomers and a useful reference source for seasoned variable star observers. With its thorough, non-mathematical descriptions of variable stars and tips for how to see them, this book enables novices and experts alike to set off into the field and observe a wide range of delightful sights. It strikes a balance between easily visible objects that can be seen in any telescope or binoculars, and variable stars that are a direct challenge to those with large aperture equipment or access to photometric tools and methods. After helping the observer differentiate between variable star types, the author goes on to explain the skills needed to operate a telescope and other equipment, as well as how to couple filters to a CCD camera or digital SLR camera in order to photometrically record these celestial objects. Further, the book includes an observational guide to 50 objects for study, with finder charts and data about light curves for ease of identification, along with the stars’ celestial coordinates, magnitudes, and other pertinent information.

Book excerpt: From #1 New York Times bestselling author Dava Sobel, the "inspiring" (People), little-known true story of women's landmark contributions to astronomy A New York Times Book Review Notable Book of 2017 Named one of the best books of the year by NPR, The Economist, Smithsonian, Nature, and NPR's Science Friday Nominated for the PEN/E.O. Wilson Literary Science Writing Award "A joy to read.” —The Wall Street Journal In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or “human computers,” to interpret the observations their male counterparts made via telescope each night. At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges—Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates. The “glass universe” of half a million plates that Harvard amassed over the ensuing decades—through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography—enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard—and Harvard’s first female department chair. Elegantly written and enriched by excerpts from letters, diaries, and memoirs, The Glass Universe is the hidden history of the women whose contributions to the burgeoning field of astronomy forever changed our understanding of the stars and our place in the universe.
