This book provides a comprehensive overview of stellar structure, evolution and basic stellar properties.
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.
Until the Apollo-Soyuz flight of 1972, the Russian Space Program was shrouded in such complete secrecy that only rumors of failures (or catastrophes) reached the West.
Written by leading exponents in the field, this collection of timely reviews presents observational methods and the latest results of astronomical research as well as their theoretical foundations and interrelations, providing information and scientifically rigorous coverage.
A thorough introduction to solar physics based on recent spacecraft observations. The author introduces the solar corona and sets it in the context of basic plasma physics before moving on to discuss plasma instabilities and plasma heating processes.
Today they can be done using self-designed spectrographs and highly efficient CCD cameras, without the need for large financial investments.This book explains the basic principles of spectroscopy, including the fundamental optical constraints and all mathematical aspects needed to understand the working principles in detail.
Beginning with basic facts about the observable universe, this book reviews the complete range of topics that make up a degree course in cosmology and particle astrophysics. This paperback edition targets students of physics, astrophysics and cosmology from advanced undergraduate to early graduate level.
This book takes a new approach on teaching the subject by following the chain of measurement through atmosphere, imaging, detection, spectroscopy, timing and hypothesis testing. It covers all wavelengths: radio, infrared, optical, UV, X-ray, gamma-ray.
Even a suitable skeptic of certain pronouncements about the age and structure of the Universe should be pleased with the large steps that have been taken in furthering our understanding of the Universe since the early 1990's. In short, the Universe of our expectations rarely matches the Universe as it is discovered.
The new edition of this comprehensive reference on astronomy observation methods and techniques includes recent developments in astronomical detectors and instrumentation, from the invention of the CCD in 1970 to the current era of huge telescopes.
This book begins by reviewing quasars, microquasars, and gamma-ray bursts and shows why black holes are responsible for them. It describes simple, isolated black holes, adding rotation, accretion, radiation and magnetic fields, to show how these objects work.
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.
Solar sail orbital dynamics and solar radiation pressure form the foundations of the book, but the engineering design of solar sails is also considered, along with potential mission applications.
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.
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.
