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.

This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IAU Colloquium No. 143 "The Sun as a Variable Star: Solar and Stellar Irradiance Variations" was held on June 20 - 25, 1993 at the Clarion Harvest House, Boulder, Colorado, USA. The main objective of this Colloquium was to review the most recent results on the observations, theoretical interpreta tions, and empirical and physical models of the variations observed in solar and stellar irradiances. A special emphasis of the Colloquium was to discuss the results gained on the climatic impact of solar irradiance variability. The study of changes in solar and stellar irradiances has been of high interest for a long time. Determining the absolute value of the luminosity of stars with different ages is a crucial question for the theory of stellar evolu tion and energy production of stellar interiors. Observations of the temporal changes of solar and stellar irradiances - in the entire spectral band and at different wavelengths - provide an additional tool for studying the physical processes below the photosphere and in the solar- stellar atmospheres. Since the Sun's radiative output is the main driver of the physical processes with in the Earth's atmosphere, the study of irradiance changes is an extremely important issue for climatic studies as well. Climatic models show that small, but persistent changes in solar irradiance may influence the Earth's climate.

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 Observer s Guide to Variable Stars written by Martin Griffiths and published by Springer. This book was released on 2018-12-06 with total page 322 pages. 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.

Download or read book Journey from the Center of the Sun written by Jack B. Zirker and published by . This book was released on 2002 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jack Zirker takes us on an imaginary voyage from the center of the sun to its surface, showing us how sunlight is made and finally following the sun's energy to the far reaches of the solar system. Along the way, he introduces the basic processes at work in our nearest star and the exciting answers solar scientists are finding to problems that have long perplexed astronomers. Journey from the Center of the Sun describes how theory and practice are coming together to provide a new understanding of this old star. At this moment, solar physicists are collecting the best observations ever obtained about the sun's interior and dynamic atmosphere, while a new breed of theorists is interpreting these data using computer simulations. Zirker reports on cutting-edge advances and looks at the tough questions solar physicists are beginning to crack. How can we account for the solar wind that causes the sun to lose mass at an astonishing rate? Where have all the neutrinos gone? How does the sun generate magnetic sunspots, and why does it have a sunspot cycle? What causes a solar flare to explode? How does the sun affect the earth's climate? What is a sunquake? For the armchair astronomer or the student of astrophysics, this book provides an unusually complete picture of solar physics today.
