The raw numbers of high-energy-density physics are amazing: shock waves at hundreds of km/s (approaching a million km per hour), temperatures of millions of degrees, and pressures that exceed 100 million atmospheres. This title surveys the production of high-energy-density conditions, the fundamental plasma and hydrodynamic models that can describe them and the problem of scaling from the laboratory to the cosmos. Connections to astrophysics are discussed throughout. The book is intended to support coursework in high-energy-density physics, to meet the needs of new researchers in this field, and also to serve as a useful reference on the fundamentals. Specifically the book has been designed to enable academics in physics, astrophysics, applied physics and engineering departments to provide in a single-course, an introduction to fluid mechanics and radiative transfer, with dramatic applications in the field of high-energy-density systems. This second edition includes pedagogic improvements to the presentation throughout and additional material on equations of state, heat waves, and ionization fronts, as well as problem sets accompanied by solutions.
This book highlights selected topics of standard and modern theory of accretion onto black holes and magnetized neutron stars. The structure of stationary standard discs and non-stationary viscous processes in accretion discs are discussed to the highest degree of accuracy analytic theory can provide, including relativistic effects in flat and warped discs around black holes. A special chapter is dedicated to a new theory of subsonic settling accretion onto a rotating magnetized neutron star. The book also describes supercritical accretion in quasars and its manifestation in lensing events. Several chapters cover the underlying physics of viscosity in astrophysical discs with some important aspects of turbulent viscosity generation. The book is aimed at specialists as well as graduate students interested in the field of theoretical astrophysics.
From superstring theory to models with extra dimensions to dark matter and dark energy, a range of theoretically stimulating ideas have evolved for physics beyond the standard model. These developments have spawned a new area of physics that centers on the interplay between particle physics and cosmology-astroparticle physics. Providing the necessary theoretical background, Particle and Astroparticle Physics clearly presents the many recent advances that have occurred in these fields. Divided into five parts, the book begins with discussions on group and field theories. The second part summarizes the standard model of particle physics and includes some extensions to the model, such as neutrino masses and CP violation. The next section focuses on grand unified theories and supersymmetry. The book then discusses the general theory of relativity, higher dimensional theories of gravity, and superstring theory. It also introduces various novel ideas and models with extra dimensions and low-scale gravity. The last part of the book deals with astroparticle physics. After an introduction to cosmology, it covers several specialized topics, including baryogenesis, dark matter, dark energy, and brane cosmology. With numerous equations and detailed references, this lucid book explores the new physics beyond the standard model, showing that particle and astroparticle physics will together reveal unique insights in the next era of physics.
Nonlinear dynamo theory is central to understanding the magnetic structures of planets, stars and galaxies.

Both kinetic and dynamic approaches to the subject are considered, including fast dynamos, topological methods in dynamo theory, physics of the solar cycle and the fundamentals of mean field dynamo. Advances in Nonlinear Dynamos is ideal for graduate students and researchers in theoretical astrophysics and applied mathematics, particularly those interested in cosmic magnetism and related topics, such as turbulence, convection, and more general nonlinear physics.
A thorough introduction to modern ideas on cosmology and on the
physical basis of the general theory of relativity, An Introduction
to the Science of Cosmology explores various theories and ideas in
big bang cosmology, providing insight into current problems.
Assuming no previous knowledge of astronomy or cosmology, this book
takes you beyond introductory texts to the point where you are able
to read and appreciate the scientific literature, which is broadly
referenced in the book. The authors present the standard big bang
theory of the universe and provide an introduction to current
inflationary cosmology, emphasizing the underlying physics without
excessive technical detail.
The eleventh COSPAR colloquium The Outer Heliosphere: The Next
Frontiers was held in Potsdam, Germany, from 24-28 July, 2000, and
is the second dedicated to this subject after the first one held in
Warsaw, Poland in 1989.
The announcement in 2012 that the Higgs boson had been discovered was understood as a watershed moment for the Standard Model of particle physics. It was deemed a triumphant event in the reductionist quest that had begun centuries ago with the ancient Greek natural philosophers. Physicists basked in the satisfaction of explaining to the world that the ultimate cause of mass in our universe had been unveiled at CERN, Switzerland. The Standard Model of particle physics is now understood by many to have arrived at a satisfactory description of entities and interactions on the smallest physical scales: elementary quarks, leptons, and intermediary gauge bosons residing within a four-dimensional spacetime continuum. Throughout the historical journey of reductionist physics, mathematics has played an increasingly dominant role. Indeed, abstract mathematics has now become indispensable in guiding our discovery of the physical world. Elementary particles are endowed with abstract existence in accordance with their appearance in complicated equations. Heisenberg's uncertainty principle, originally intended to estimate practical measurement uncertainties, now bequeaths a numerical fuzziness to the structure of reality. Particle physicists have borrowed effective mathematical tools originally invented and employed by condensed matter physicists to approximate the complex structures and dynamics of solids and liquids and bestowed on them the authority to define basic physical reality. The discovery of the Higgs boson was a result of these kinds of strategies, used by particle physicists to take the latest steps on the reductionist quest. This book offers a constructive critique of the modern orthodoxy into which all aspiring young physicists are now trained, that the ever-evolving mathematical models of modern physics are leading us toward a truer understanding of the real physical world. The authors propose that among modern physicists, physical realism has been largely replaced-in actual practice-by quasirealism, a problematic philosophical approach that interprets the statements of abstract, effective mathematical models as providing direct information about reality. History may judge that physics in the twentieth century, despite its seeming successes, involved a profound deviation from the historical reductionist voyage to fathom the mysteries of the physical universe.
Here is a fascinating reader-friendly exploration of "the phosphorus enigma." The volume attempts to answer the questions: How did phosphorus atoms, which are produced inside the inner cores of a handful of huge stars, become concentrated in relatively high proportions in the organisms composing Earth's biosphere? And how did these phosphate derivatives manage to be included in such a great variety of organic molecules playing essential biochemical roles in all known life forms? Due to the interdisciplinary nature of the topic, the volume is arranged in three sections. The first section introduces the fundamental concepts and notions of physics, chemistry, and biology necessary for the proper understanding of the topics discussed within an astronomical framework. The author then focuses on the role of phosphorus and its compounds within the context of chemical evolution in galaxies, considering its relevance in most essential biochemical functions as well as its peculiar chemistry under different physicochemical conditions. The third section provides an overall perspective on the role of phosphorus and its compounds in current areas of research of solid state physics, materials engineering, nanotechnology or medicine.

Gravitational waves (GWs) are a hot topic and promise to play a
central role in astrophysics, cosmology, and theoretical physics.
Technological developments have led us to the brink of their direct
observation, which could become a reality in the coming years. The
direct observation of GWs will open an entirely new field: GW
astronomy. This is expected to bring a revolution in our knowledge
of the universe by allowing the observation of previously unseen
phenomena, such as the coalescence of compact objects (neutron
stars and black holes), the fall of stars into supermassive black
holes, stellar core collapses, big-bang relics, and the new and
unexpected.
Dusty or complex plasmas are plasmas containing solid or liquid charged particles referred to as dust. Naturally occurring in space, they are present in planetary rings and comet tails, as well as clouds found in the vicinity of artificial satellites and space stations. On a more earthly level, dusty plasmas are now being actively researched as dust plays a key role in technological plasma applications associated with etching technologies in microelectronics, as well as with production of thin films and nanoparticles. Complex and Dusty Plasmas: From Laboratory to Space provides a balanced and consistent picture of the current status of the field by covering new developments in experimental and theoretical research. Drawing from research performed across the earth and even beyond by an internationally diverse group of pioneering researchers, this book covers a wealth of topics. It delves into: Major types of complex plasmas in ground-based and microgravity experiments Properties of the magnetized, thermal, cryogenic, ultraviolet, nuclear-induced complex plasmas and plasmas with nonspherical particles Major forces acting on the particles and features of the particle dynamics in complex plasmas, as well as basic plasma-particle interactions, Recent research results on phase transitions between crystalline and liquid complex plasma states Astrophysical aspects of dusty plasmas and numerical simulation of their properties Dust as a source of contamination in many applications including reactors An important feature of this work is the detailed discussion of unique experimental and theoretical aspects of complex plasmas related to the investigations under microgravity conditions performed onboard Mir and ISS space stations. Much of what we know today would not be

SI units are used for physical data and in conversions of astronomical quantities. This book is one of the few to use real rather than idealized or simplified data in the problems.
The origin of the solar system has been a matter of speculation for
many centuries, and since the time of Newton it has been possible
to apply scientific principles to the problem. A succession of
theories, starting with that of Pierre Laplace in 1796, has gained
general acceptance, only to fall from favor due to its
contradiction in some basic scientific principle or new heavenly
observation. Modern observations by spacecraft of the solar system,
the stars, and extra-solar planetary systems continuously provide
new information that may be helpful in finding a plausible theory
as well as present new constraints for any such theory to satisfy.

Edwin Hubble: Mariner of the Nebulae is both the biography of an extraordinary human being and the story of the greatest quest in the history of astronomy since the Copernican revolution. The book is a revealing portrait of scientific genius, an incisive engaging history of ideas, and a shimmering evocation of what we see when gazing at the stars. Born in 1889 and reared in the village of Marshfield, Missouri, Edwin Powell Hubble-star athlete, Rhodes Scholar, military officer, and astronomer- became one of the towering figures in twentieth-century science. Hubble worked with the great 100-inch Hooker telescope at California's Mount Wilson Observatory and made a series of discoveries that revolutionized humanity's vision of the cosmos. In 1923 he was able to confirm the existence of other nebulae (now known to be galaxies) beyond our own Milky Way. By the end of the decade, Hubble had proven that the universe is expanding, thus laying the very cornerstone of the big bang theory of creation. It was Hubble who developed the elegant scheme by which the galaxies are classified as ellipticals and spirals, and it was Hubble who first provided reliable evidence that the universe is homogeneous, the same in all directions as far as the telescope can see. An incurable Anglophile with a penchant for tweed jackets and English briars, Hubble, together with his brilliant and witty wife, Grace Burke, became a fixture in Hollywood society in the 1930s and 40s. They counted among their friends Charlie Chaplin, the Marx brothers, Anita Loos, Aldous and Maria Huxley, Walt Disney, Helen Hayes, and William Randolph Hearst. Albert Einstein, a frequent visitor to Southern California, called Hubble's work "beautiful" and modified his equations on relativity to account for the discovery that the cosmos is expanding.
Black holes are becoming increasingly important in contemporary research in astrophysics, cosmology, theoretical physics, and mathematics. Indeed, they provoke some of the most fascinating questions in fundamental physics, which may lead to revolutions in scientific thought. Written by distinguished scientists, Classical and Quantum Black Holes provides a comprehensive panorama of black hole physics and mathematics from a modern point of view. The book begins with a general introduction, followed by five parts that cover several modern aspects of the subject, ranging from the observational and the experimental to the more theoretical and mathematical issues. The material is written at a level suitable for postgraduate students entering the field.
Research of the interstellar medium (ISM) has been advancing
rapidly during the last 10 years, mainly due to immensely improved
observational facilities and techniques in all wavelength ranges.
We are now able to investigate the ISM in external galaxies and
even the intergalactic and intracluster medium in great detail.
Increased spatial and spectral resolution have provided us with a
great deal of information on the interstellar gas in its various
phases, the magnetic field and the cosmic rays, and of course, also
the stellar component, which is the driving agent of the
interstellar matter cycle.
Reflecting the results of twenty years; experience in the field of
multipurpose flights, this monograph includes the complex routes of
the trajectories of a number of bodies (e.g., space vehicles,
comets) in the solar system.
As demonstrated by five Nobel Prizes in physics, radio astronomy has contributed greatly to our understanding of the Universe. Yet for too long, there has been no comprehensive textbook on radio astronomy for undergraduate students. This two-volume set of introductory textbooks is exclusively devoted to radio astronomy, with extensive discussions of telescopes, observation methods, and astrophysical processes that are relevant for this exciting field. The first volume, Fundamentals of Radio Astronomy: Observational Methods, discusses radio astronomy instrumentation and the techniques to conduct successful observations. The second volume, Fundamentals of Radio Astronomy: Astrophysics, discusses the physical processes that give rise to radio emission, presents examples of astronomical objects that emit by these mechanisms, and illustrates how the relevant physical parameters of astronomical sources can be obtained from the radio observations. Requiring no prior knowledge of astronomy, the two volumes are ideal textbooks for radio astronomy courses at the undergraduate or graduate level, particularly those that emphasize radio wavelength instrumentation and observational techniques or the astrophysics of radio sources. The set enables instructors to pick and choose topics from the two volumes that best fit their courses. Features: Explores radio astronomy instruments and techniques that are important to enable observations Describes astrophysical processes that produce the radio emissions observed in different types of astronomical objects Includes numerous worked examples to demonstrate how the methods are used to solve problems, in addition to advanced material for students with more extensive physics and mathematics backgrounds

Ideas and Methods of Supersymmetry and Supergravity: Or a Walk Through Superspace provides a comprehensive, detailed, and self-contained account of four dimensional simple supersymmetry and supergravity. Throughout the book, the authors cultivate their material in detail with calculations and full discussions of the fundamental ideas and motivations. They develop the subject in its superfield formulations but where appropriate for illustration, analogy, and comparison with conventional field theory, they use the component formulation. The book discusses many subjects that, until now, can only be found in the research literature. In addition, it presents a plethora of new results. Combining classical and quantum field theory with group theory, differential geometry, and algebra, the book begins with a solid mathematical background that is used in the rest of the book. The next chapter covers algebraic aspects of supersymmetry and the concepts of superspace and superfield. In the following chapters, the book presents classical and quantum superfield theory and the superfield formulation of supergravity. A synthesis of results and methods developed in the book, the final chapter concludes with the theory of effective action in curved superspaces. After studying this book, readers should be well prepared to pursue independent research in any area of supersymmetry and supergravity. It will be an indispensable source of reference for advanced graduate students, postdoctoral faculty, and researchers involved in quantum field theory, high energy physics, gravity theory, mathematical physics, and applied mathematics.
This book builds on the fluid and kinetic theory of equilibria and waves presented in a companion textbook, Basic Space Plasma Physics (by the same authors), but can also serve as a stand-alone text. It extends the field covered there into the domain of plasma instability and nonlinear theory. The book provides a representative selection of the many possible macro- and microinstabilities in a space plasma, from the Rayleigh-Taylor and Kelvin-Helmholtz to electrostatic and electromagnetic kinetic instabilities. Their quasilinear stabilization and nonlinear evolution and their application to space physics problems are treated. The chapters on nonlinear theory include nonlinear waves, weak turbulence and strong turbulence, all presented from the viewpoint of their relevance to space plasma physics. Special topics include auroral particle acceleration, soliton formation and caviton collapse, anomalous transport, and the theory of collisionless shocks. |
