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.
Download or read book The Sky is Your Laboratory written by Robert Buchheim and published by Springer Science & Business Media. This book was released on 2007-07-31 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the experienced amateur astronomer who is wondering if there is something useful, valuable, and permanent that can be done with his or her observational skills, the answer is, “Yes, there is!” This is THE book for the amateur astronomer who is ready to take the next step in his or her astronomical journey. Till now there has been no text that points curious amateur astronomers to the research possibilities open to them. At the 2006 meeting of the Society for Astronomical Sciences, participants agreed that the lack of such a text was a serious gap in the astronomical book market. This book plugs that hole.

Download or read book Information Handling in Astronomy written by Andre Heck and published by Springer Science & Business Media. This book was released on 2000-10-31 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pilot boat just moved away and'its lights are already fading towards the coast of Northeastern Queensland over which Saturn is going to set. There is still quite some time to go before dawn. The big ship has now regained her cruise speed following its roughly northwesterly route in the South Coral Sea along the chain of nearby reefs. Few people are around at this time, except a dozen early birds sharing some 'shipshaping' exercise on the top deck and taking advantage of the relative coolness of the night. On my way down to the stateroom, I cannot but stop once more in front of that elegant composition by British artist Brigid Collins (1963-) hanging in the monumental staircase between Decks 7 and 8. That piece 2 of art, a 1.8x 1.8m oil on canvas plus collage entitled Berinl in honour of the Danish explorer, gathers together many navigation-related themes of the time: Suns, Moons, planets, sky maps, astrolabes, small telescopes, as well as drawings, diagrams and charts of all kinds. It is somehow a digest of how astronomical information was then collected, made available, and used.
Download or read book Forgotten Civilization written by Robert M. Schoch and published by Simon and Schuster. This book was released on 2021-03-02 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Updated throughout with recent developments and additional illustrations • Reveals how solar outbursts caused the end of the last ice age, unleashed catastrophe upon ancient advanced civilizations, and led to six millennia of a Solar-Induced Dark Age • Includes evidence from solar science, geology, oceanic circulation patterns, the Sphinx, the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Göbekli Tepe complex in Turkey In this newly revised and expanded edition, updated throughout with recent developments, geologist Robert Schoch builds upon his revolutionary theory that the origins of the Sphinx date back much further than 2500 BCE and examines scientific evidence of the catastrophe that destroyed early high culture nearly 12,000 years ago. Combining evidence from multiple scientific disciplines, Schoch makes the case that the abrupt end of the last ice age, circa 9700 BCE, was due to an agitated Sun. Solar outbursts unleashed electrical/plasma discharges upon Earth, triggering dramatic climate change as well as increased earthquake and volcanic activity, fires, high radiation levels, and massive floods. Schoch explains how these events impacted the civilizations of the time, set humanity back thousands of years, and led to six millennia of a Solar-Induced Dark Age (SIDA). Applying the SIDA framework to ancient history, he explores how many megalithic monuments, petroglyphs, indigenous traditions, and legends fall logically into place, including the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Göbekli Tepe complex in Turkey. He also reveals that our Sun is a much more unstable star than previously believed, suggesting that history could repeat itself with a solar outburst powerful enough to devastate modern society. Weaving together a new view of the origins and antiquity of civilization and the dynamics of the planet we live on, Schoch maintains we must heed the megalithic warning of the past and collectively prepare for future events.

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.

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.
Download or read book Observing the Sun written by Jamey L. Jenkins and published by Springer Science & Business Media. This book was released on 2013-07-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Observing the Sun” is for amateur astronomers at all three levels: beginning, intermediate, and advanced. The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun. Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations. Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. “Observing the Sun” provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun.

Download or read book Flash written by Govert Schilling and published by Cambridge University Press. This book was released on 2002-04-18 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin and nature of gamma-ray bursts is currently one of the greatest mysteries in astrophysics. These tremendously powerful blasts produce more energy in a fraction of a second than our Sun does in ten billion years. Since their accidental discovery by American spy satellites over thirty years ago, astronomers have striven to understand these enigmatic explosions. It is only recently, thanks to an Italian-Dutch satellite, and powerful telescopes both on the ground and in space, that the mystery is beginning to be unravelled. Astronomers now realise that gamma-ray bursts are probably related to the birth of black holes in extremely distant galaxies. Flash! describes the fast moving field of gamma ray burst research, from the initial detection right up to the most recent discoveries. Based on interviews with leading scientists, this exciting book provides an inside view of the scientific challenges involved in unravelling the mystery of gamma-ray bursts.
