Bücher der Reihe Astronomy and Planetary Sciences

Understanding how the Sun changes though its 11-year sunspot cycle and how these changes affect the vast space around the Sun - the heliosphere - has been one of the principal objectives of space research since the advent of the space age.

The main theme of the book is the presentation of techniques used to identify chaotic behavior in the evolution of conservative mechanical systems and their application to astronomical systems. It results from graduate courses given by the author over the years both at university and at several international summer schools.Along the book surfaces of section, Lyapunov characteristic exponents, frequency maps, MEGNO, dense grid maps, etc., are presented and discussed in connection with the applications. The initial chapter is devoted to the presentation of the main ideas of the chaotic dynamics of conservative systems in plain language so that they can be accessible to a wide range of professionals and students of physical sciences. The applications are mainly related to the motions in the solar system and extrasolar planetary systems.Another chapter is devoted to the applications to asteroids showing how the asteroidal belt is sculpted by chaos and resonances. The contrasting existence of gaps in the distribution of the asteroids and groups of asteroids in resonances is thoroughly discussed. The interest in applications to planetary systems is growing since the discovery of systems of resonant planets around some stars of the solar neighborhood. Exoplanets added a lot of cases to a problem that was before restricted to the planets of our solar system. The book includes an account of results already existing about compact systems.

"e;Astrophysics Updates"e; is intended to serve the information needs of professional astronomers and postgraduate students about areas of astronomy, astrophysics and cosmology that are rich and active research spheres. Observational methods and the latest results of astronomical research are presented as well as their theoretical foundations and interrelations. The contributed commissioned articles are written by leading exponents in a format that will appeal to professional astronomers and astrophysicists who are interested in topics outside their own specific areas of research. This collection of timely reviews may also attract the interest of advanced amateur astronomers seeking scientifically rigorous coverage.

The Ulysses observations have charted the heliosphere around the minimum in the 11 year cycle of solar activity, revealing the large scale properties of the heliospheric medium and its micro-scale characteristics. This book presents for the first time, a comprehensive review of the results of the Ulysses mission.The first chapter provides an overview of the region, introducing the heliosphere prior to the Ulysses mission, and the objectives and characteristics of the mission itself. Subsequent chapters discuss in detail specific areas of the heliosphere, including the solar wind, large and small scale features, cosmic rays and energetic particles, and the observations of interstellar gas and cosmic dust. Each of these chapters is written by members of the Ulysses science team, concentrating on their own areas of expertise, and is written in a clear and accessible way.In this book, the authors aim to summarise our understanding of the heliosphere near solar minimum and to provide the basis for understanding the more complex state of the heliosphere around solar maximum, which will be observed during the next phase of the Ulysses mission.

This book provides an up-to-date interdisciplinary geoscience-focused overview of solid solar system bodies and their evolution, based on the comparative description of processes acting on them.Planetary research today is a strongly multidisciplinary endeavor with efforts coming from engineering and natural sciences. Key focal areas of study are the solid surfaces found in our Solar System. Some have a direct interaction with the interplanetary medium and others have dynamic atmospheres. In any of those cases, the geological records of those surfaces (and sub-surfaces) are key to understanding the Solar System as a whole: its evolution and the planetary perspective of our own planet.This book has a modular structure and is divided into 4 sections comprising 15 chapters in total. Each section builds upon the previous one but is also self-standing. The sections are: Methods and toolsProcesses and Sources Integration and Geological SynthesesFrontiersThe latter covers the far-reaching broad topics of exobiology, early life, extreme environments and planetary resources, all areas where major advancements are expected in the forthcoming decades and both key to human exploration of the Solar System.The target readership includes advanced undergraduate students in geoscience-related topics with no specific planetary science knowledge; undergraduates in other natural science domains (e.g. physics, astronomy, biology or chemistry); graduates in engineering and space systems design who want to complement their knowledge in planetary science.The authors' backgrounds span a broad range of topics and disciplines: rooted in Earth geoscience, their expertise covers remote sensing and cartography, field mapping, impact cratering, volcanology and tectonics, sedimentology and stratigraphy exobiology and life in extreme environments, planetary resources and mining. Several generations of planetary scientists are cooperating to provide a modern view on a discipline developed from Earth during and through Space exploration.

Markus Aschwanden introduces the concept of self-organized criticality (SOC) and shows that due to its universality and ubiquity it is a law of nature for which he derives the theoretical framework and specific physical models in this book.

This book offers a uniform collection of probe and CCD terrestrial images for each lunar dome, and presents information on morphological measurements and rheologic properties including a novel classification system and a new map of the distribution of domes.

Examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. Considers exotic forms of life that would not have to rely on carbon as the basic chemical element, solar energy as the main energy source, or water as the primary solvent and the question of detecting bio- and geosignatures of such life forms, ranging from earth environments to deep space.Seeks an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter. Avoids scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.

This textbook looks at gravitational lensing, which has become an invaluable tool in modern astrophysics, from finding planets orbiting distant stars to understanding how dark matter and dark energy conspired to form the galaxies and cosmic structures we see today. Principles of Gravitational Lensing begins with EinsteinΓÇÖs prediction that mass bends light, and shows how this simple idea has gone from theoretical curiosity to observational science in under a century. It describes how the three subfields known as strong lensing, weak lensing, and microlensing have grown independently but become increasingly intertwined. Drawing on their research experience, Congdon and Keeton present the mathematical foundation of gravitational lensing to beginning graduate and advanced undergraduate students with a background in physics. The derivations and explanations are supplemented by exercises at the end of each chapter. The treatment is self-contained and comprehensive. Principles of Gravitational Lensing is ideal for students and seasoned researchers looking to penetrate this thriving subject and even contribute research of their own. Certain properties of stars and planets could be seen with the naked eye, but the full beauty and complexity of the cosmos was revealed only with the advent of the telescope. Today, astronomers recognize that gravity can bend light rays, creating enormous ΓÇ£cosmic telescopesΓÇ¥ that help us probe aspects of the universe that are otherwise invisible. While various monographs and lecture compilations on the subject have appeared, a comprehensive didactic account that assumes only a background in undergraduate physics has so far been lacking. This book begins with the basic physics of light bending and builds up to current research topics in a clear and systematic way. Relevant background material from physics and mathematics is included, making the book self-contained. Exercises at the end of each chapter are carefully designed to help students master the theoretical concepts and methods that drive research in gravitational lensing. An extensive bibliography guides those wishing to delve more deeply into particular areas of interest.
