Book Synopsis Solar and Stellar Variability (IAU S264) by : Alexander G. Kosovichev
Download or read book Solar and Stellar Variability (IAU S264) written by Alexander G. Kosovichev and published by Cambridge University Press. This book was released on 2010-03-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the physical mechanisms of solar variability and its effect on Earth and the planets is a central and long-standing problem of astronomy and astrophysics. Variability of a similar nature has been observed in other stars, and investigating their similarities and differences is essential to helping us understand the underlying mechanisms and their impacts on planets. During the past decade multi-wavelength data from several solar and stellar space missions, together with ground-based observations, have provided tremendous amounts of new information about the physical processes on the Sun and solar-type stars. Solar observations have revealed interesting connections between the cyclic variations of the structure, interior dynamics, surface magnetism and coronal phenomena, but it is still unclear where and how magnetic fields are generated in the Sun, and why it has a regular 22-year magnetic cycle. IAU Symposium 264 discusses key observational results, new theoretical ideas and models which address these subjects.
Book Synopsis Solar and Stellar Flares and their Effects on Planets (IAU S320) by : Alexander G. Kosovichev
Download or read book Solar and Stellar Flares and their Effects on Planets (IAU S320) written by Alexander G. Kosovichev and published by Cambridge University Press. This book was released on 2016-09-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in observations and modelling of solar and stellar flares have opened up new perspectives for understanding the fundamental physical mechanisms of magnetic energy storage and release, particle acceleration, and their radiative and dynamical processes. New interest in this topic is stimulated by Kepler observations and the discovery of superflares on solar-type stars, which raises questions about the possibility of such flares on the Sun, and the potential effects of superflares on terrestrial and extraterrestrial planets, including their impact on the origin and evolution of life. IAU Symposium 320 discusses the recent advances in observations and theories of solar and stellar flares, focusing on the understanding of their phenomenological and physical aspects, as well as consequences for terrestrial planets and exoplanets. This volume will be useful to researchers of all levels working in this fascinating and rapidly developing field of astronomy.

Book Synopsis Cosmic Magnetism, by : Percy Seymour
Download or read book Cosmic Magnetism, written by Percy Seymour and published by CRC Press. This book was released on 1986 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of extraterrestrial magnetic fields is a relatively new one, confirmation of the existance of the first such field (that of our Sun) having come a s late as 1908. In the past 30 years a great ammount of knowledge has been accumulated on Cosmic Magnetism, which has turned out to be a truly fascinating topic for study. Percy Seymour's book is the first to deal with the topic in a non-mathematical way, and he offers a fine introduction to his subject. The first three chapters consolidate our knowledge on magnetism in general and the magnetic field of the Earth, as well as discussing the reasons for studying astronomy and cosmic magnetism in particular. The remainder of the book is devoted to the main areas of cosmic magnetism - solar, plantetary and interplanetary fields, fields in stars and pulsars, fields of the milky way and fields in other galaxies. Cosmic Magnetism in an ideal book for sixth-formers and undergraduates studying physics or astronomy and will also appeal to amateur astronomers. as previous work on this topic has been 'hidden' in specialised academic journals.
Book Synopsis Stellar Collapse by : Chris L. Fryer
Download or read book Stellar Collapse written by Chris L. Fryer and published by Springer Science & Business Media. This book was released on 2004-04-30 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supernovae, hypernovae and gamma-ray bursts are among the most energetic explosions in the universe. The light from these outbursts is, for a brief time, comparable to billions of stars and can outshine the host galaxy within which the explosions reside. Most of the heavy elements in the universe are formed within these energetic explosions. Surprisingly enough, the collapse of massive stars is the primary source of not just one, but all three of these explosions. As all of these explosions arise from stellar collapse, to understand one requires an understanding of the others. Stellar Collapse marks the first book to combine discussions of all three phenomena, focusing on the similarities and differences between them. Designed for graduate students and scientists newly entering this field, this book provides a review not only of these explosions, but the detailed physical models used to explain them from the numerical techniques used to model neutrino transport and gamma-ray transport to the detailed nuclear physics behind the evolution of the collapse to the observations that have led to these three classes of explosions.
Book Synopsis Physics of the Plasma Universe by : Anthony L. Peratt
Download or read book Physics of the Plasma Universe written by Anthony L. Peratt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade our understanding of plasma physics has witnessed an explosive growth due to research in two areas: work directed toward controlled nuclear fusion and work in space physics. This book addresses the growing need to apply these complementary discoveries to astrophysics. Today plasma is recognized as the key element to understanding the generation of magnetic fields in planets, stars and galaxies, the accel- eration and transport of cosmic rays, and many other phenomena occurring in interstellar space, in radio galaxies, stellar atmospheres, quasars, and so forth.

Book Synopsis Nonlinear Cosmic Ray Diffusion Theories by : Andreas Shalchi
Download or read book Nonlinear Cosmic Ray Diffusion Theories written by Andreas Shalchi and published by Springer Science & Business Media. This book was released on 2009-06-04 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: If charged particles move through the interplanetary or interstellar medium, they interact with a large-scale magnetic ?eld such as the magnetic ?eld of the Sun or the Galactic magnetic ?eld. As these background ?elds are usually nearly constant in time and space, they can be approximated by a homogeneous ?eld. If there are no additional ?elds, the particle trajectory is a perfect helix along which the par- cle moves at a constant speed. In reality, however, there are turbulent electric and magnetic?elds dueto the interstellaror solar wind plasma. These ?elds lead to sc- tering of the cosmic rays parallel and perpendicular to the background ?eld. These scattering effects, which usually are of diffusive nature, can be described by s- tial diffusion coef?cients or, alternatively, by mean free paths. The knowledge of these parameters is essential for describing cosmic ray propagation as well as d- fusive shock acceleration. The latter process is responsible for the high cosmic ray energies that have been observed. The layout of this book is as follows. In Chap. 1, the general physical scenario is presented. We discuss fundamental processes such as cosmic ray propagation and acceleration in different systems such as the solar system or the interst- lar space. These processes are a consequence of the interaction between charged cosmic particles and an astrophysical plasma (turbulence). The properties of such plasmas are therefore the subject of Chap. 2.
Book Synopsis Corotating Interaction Regions by : A. Balogh
Download or read book Corotating Interaction Regions written by A. Balogh and published by Springer Science & Business Media. This book was released on 2000-01-31 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gives a comprehensive and integrated overview of current knowledge and understanding of corotating interaction regions (CIRs) in the solar wind. It is the result of a workshop at ISSI, where space scientists involved in the Ulysses, Pioneer, Voyager, IMP-8, Wind, and SOHO missions exchanged their data and interpretations with theorists in the fields of solar and heliospheric physics. The book provides a broad synthesis of current understanding of CIRs, which form at the interface between the fast solar wind originating in the northern and southern coronal holes and the slow solar wind that originates near and within coronal streamers surrounding the heliomagnetic equator. CIRs are the dominant structure in the heliosphere near and beyond Earth on the declining phase and near the minimum of the 11-year solar activity cycle. Particles energized at the shocks that bound CIRs at heliospheric distances beyond the orbit of Earth are the dominant energetic particle population observed in the outer heliosphere at these times. Papers included in this volume cover the subject of CIRs from their dissipation in the outer hemisphere, and include discussions of complexities associated with their evolution with distance from the Sun, their three-dimensional structure, and the myriad effects that CIRs have on energetic particles throughout the heliosphere. The book is intended to provide scientists active in space physics research with an up-to-date status report on current understanding of CIRs and their effects in the heliosphere, and also to serve the advanced graduate student with introductory material on this active field of research.

Download or read book Storms of My Grandchildren written by James Hansen and published by A&C Black. This book was released on 2011-01-04 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: _______________ 'When the history of the climate crisis is written, Hansen will be seen as the scientist with the most powerful and consistent voice calling for intelligent action to preserve our planet's environment' - Al Gore 'Few people know more about climate change than James Hansen ... This unnerving and fluently written book is the definitive one to read' - BBC Wildlife 'Anyone concerned about the world our children and grandchildren must inherit owes it to themselves to read this book' - Irish Times _______________ An urgent and provocative call to action from the world's leading climate scientist Dr James Hansen, the world's leading scientist on climate issues, speaks out with the full truth about global warming: the planet is hurtling to a climatic point of no return. Hansen - whose climate predictions have come to pass again and again, beginning in the 1980s when he first warned US Congress about global warming - is the single most credible voice on the subject worldwide. He paints a devastating but all-too-realistic picture of what will happen if we continue to follow the course we're on. But he is also a hard-headed optimist, and shows that there is still time to take the urgent, strong action needed to save humanity. _______________ 'James Hansen gives us the opportunity to watch a scientist who is sick of silence and compromise; a scientist at the breaking point - the point at which he is willing to sacrifice his credibility to make a stand to avert disaster' - LA Times

Book Synopsis Timing Neutron Stars: Pulsations, Oscillations and Explosions by : Tomaso M. Belloni
Download or read book Timing Neutron Stars: Pulsations, Oscillations and Explosions written by Tomaso M. Belloni and published by Springer Nature. This book was released on 2020-10-23 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron stars, whether isolated or in a binary system, display a varied and complex phenomenology, often accompanied by extreme variability of many time scales, which takes the form of pulsations due to the object rotation, quasi-periodicities associated to accretion of matter, and explosions due to matter accreted on the surface or to starquakes of highly magnetized objects. This book gives an overview of the current observational and theoretical standpoint in the research on the physics under the extreme conditions that neutron stars naturally provide. The six chapters explore three physical regions of a neutron star: the space around it, where accretion and pulsar companions allow testing of general relativity its surface, where millisecond pulsation and X-ray burts provide clues about general relativistic effects and the equation of state of neutron matter its interior, of course, inaccessible to direct observations, can nevertheless, be probed with all observational parameters related to neutron star variability.

Book Synopsis Enceladus and the Icy Moons of Saturn by : Paul M. Schenk
Download or read book Enceladus and the Icy Moons of Saturn written by Paul M. Schenk and published by University of Arizona Press. This book was released on 2018-11-27 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: With active geysers coating its surface with dazzlingly bright ice crystals, Saturn’s large moon Enceladus is one of the most enigmatic worlds in our solar system. Underlying this activity are numerous further discoveries by the Cassini spacecraft, tantalizing us with evidence that Enceladus harbors a subsurface ocean of liquid water. Enceladus is thus newly realized as a forefront candidate among potentially habitable ocean worlds in our own solar system, although it is only one of a family of icy moons orbiting the giant ringed planet, each with its own story. As a new volume in the Space Science Series, Enceladus and the Icy Moons of Saturn brings together nearly eighty of the world’s top experts writing more than twenty chapters to set the foundation for what we currently understand, while building the framework for the highest-priority questions to be addressed through ongoing spacecraft exploration. Topics include the physics and processes driving the geologic and geophysical phenomena of icy worlds, including, but not limited to, ring-moon interactions, interior melting due to tidal heating, ejection and reaccretion of vapor and particulates, ice tectonics, and cryovolcanism. By contextualizing each topic within the profusion of puzzles beckoning from among Saturn’s many dozen moons, Enceladus and the Icy Moons of Saturn synthesizes planetary processes on a broad scale to inform and propel both seasoned researchers and students toward achieving new advances in the coming decade and beyond.
