Accretion disks in compact stellar systems containing white dwarfs, neutron stars or black holes are the principal laboratory for understanding the role of accretion disks in a wide variety of environments from proto-stars to quasars. Recent work on disk instabilities and dynamics has given a new theoretical framework with which to study accretion disks. Modeling of time-dependent phenomena provides new insight into the causes and interpretation of photometric and spectroscopic variability and new constraints on the fundamental physical problem — the origin of viscosity in accretion disks. This book contains expert reviews on the nature of limit cycle thermal instabilities and a variety of closely related topics from the theory of angular momentum transport to eclipse mapping of the disk structure. The result is a comprehensive contemporary survey of the structure and evolution of accretion disks in compact binary systems.

It has been more than fifty years since the first significant paper on accretion flows was written. In recent years, X-ray satellites capable of identifying accretion disks and radiation jets - indications that accretion has taken place - have significantly advanced our understanding of these phenomena. This volume presents a comprehensive and up-to-date introduction to the major theoretical and observational topics associated with accretion processes in astrophysics. Comprising lectures presented at the twenty-first Winter School of the Canary Islands Institute of Astrophysics, the text emphasises the physical aspects of accretion, investigating how radiation jets are produced, how accretion power is divided between jets and radiated energy, the geometry of accretion flow, and the accretion processes of active galactic nuclei. Written by an international team of experienced scientists, chapters offer young researchers key analytical tools for supporting and carrying out the next generation of front-line research.

This textbook introduces the current astrophysical observations of black holes, and discusses the leading techniques to study the strong gravity region around these objects with electromagnetic radiation. More importantly, it provides the basic tools for writing an astrophysical code and testing the Kerr paradigm. Astrophysical black holes are an ideal laboratory for testing strong gravity. According to general relativity, the spacetime geometry around these objects should be well described by the Kerr solution. The electromagnetic radiation emitted by the gas in the inner part of the accretion disk can probe the metric of the strong gravity region and test the Kerr black hole hypothesis. With exercises and examples in each chapter, as well as calculations and analytical details in the appendix, the book is especially useful to the beginners or graduate students who are familiar with general relativity while they do not have any background in astronomy or astrophysics.“/p>

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.

High resolution is a key element in research in astronomy and cosmology. Advances in instrumentation and new methods are enabling us to constantly make new exciting discoveries, and progress in theoretical modelling allows us to gain a deeper understanding of cosmic physics. One example of this progress in instrumentation and observing strategy have made possible the discovery of a rich population of low-mass planets orbiting solar-type stars (Michel Mayor et al., Karl Schwarzschild Lecture 2010). This 23rd volume in the series Reviews of Modern Astronomy contains 14 invited reviews and highlight contributions presented during the 2010 annual meeting of the Astronomical Society on the topic "Zooming in: The cosmos at high resolution", held in Bonn, Germany, in September 2010.

The book reviews the present status of understanding the nature of the most luminous objects in the Universe, connected with supermassive black holes and supermassive stars, clusters of galaxies and ultraluminous galaxies, sources of gamma-ray bursts and relativistic jets. Leading experts give overviews of essential physical mechanisms involved, discuss formation and evolution of these objects as well as prospects for their use in cosmology, as probes of the intergalactic medium at high redshifts and as a tool to study the end of dark ages. The theoretical models are complemented by new exciting results from orbital and ground-based observatories such as Chandra, XMM-Newton, HST, SDSS, VLT, Keck, and many others.
