Theory of Accretion Disks by F. Meyer,Wolfgang J. Duschl,Juhan Frank,Emmi Meyer-Hofmeister Pdf
With the advent of space observatories and modern developments in ground based astronomy and concurrent progress in the theoretical understanding of these observations it has become clear that accretion of material on to compact objects is an ubiquitous mechanism powering very diverse astrophysical sources ranging in size and luminosity by many orders of magnitude. A problem common to these systems is that the material accreted must in general get rid of its angular momentum and this leads to the formation of an Accretion Disk which allows angular momentum re-distribution and converts potential energy into radiation with an efficiency which can be higher than the nuclear burning yield. These systems range in size from quasars and active galactic nuclei to accretion disks around forming stars and the early solar system and to compact binaries such as cataclysmic variables and low-mass X-ray binaries. Other objects that should be mentioned in this context are 88433, the black hole binary candidates, and possibly gamma-ray burst sources. Observations of these systems have provided important constraints for theoretical accretion disk models on widely differing scales, lumi nosities, mass-transfer rates and physical environments.
Dynamics of Astrophysical Discs by J. A. Sellwood Pdf
Covers recent developments in both theory and observations of discs in a wide variety of astrophysical contexts. The volume is based on a conference held at the University of Manchester in 1988, which brought together an international group of experts in a wide range of fields. The papers cover planetary ring systems, discs in star-forming regions, protoplanetary discs, accretion and galaxy discs--areas related by the remarkable similarity between the dynamical problems posed by each type of disc. This will be a valuable reference work for researchers and postgraduate students in many branches of astronomy.
Theory of Black Hole Accretion Discs by Marek A. Abramowicz,Gunnlaugur Björnsson,James E. Pringle Pdf
The first comprehensive and up-to-date review of our new understanding of accretion disks around black holes - with chapters from experts from around the world.
Advection-dominated disks are replacing the standard model, and this book provides the first extensive examination of their various aspects. Topics discussed include the global disk structure, thermal stability, two-temperature regimes, electron-positron pair production, disk spectra, the relation to the outburst behaviour of X-ray transients and hard-soft spectral transitions, the effects of radiation drag force, jet formation and possible nucleosynthesis in the advection-dominated disks. The papers also address some more fundamental issues concerning the basic physics of accretion disks, including the origin of disk viscosity, the observational appearance of the tidal instability. In cataclysmic variables, and the role of self-gravity of accretion disks in relation to stellar systems and to star/planet formation. This book will be required reading for any astronomer, cosmologist or astrophysicist seeking an up-to-date overview of this topic.
Accretion Flows in Astrophysics by Nikolay Shakura Pdf
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.

Physical Processes in Circumstellar Disks Around Young Stars by Paulo J. V. Garcia Pdf
Circumstellar disks are vast expanses of dust that form around new stars in the earliest stages of their birth. Predicted by astronomers as early as the eighteenth century, they weren’t observed until the late twentieth century, when interstellar imaging technology enabled us to see nascent stars hundreds of light years away. Since then, circumstellar disks have become an area of intense study among astrophysicists, largely because they are thought to be the forerunners of planetary systems like our own—the possible birthplaces of planets. This volume brings together a team of leading experts to distill the most up-to-date knowledge of circumstellar disks into a clear introductory volume. Understanding circumstellar disks requires a broad range of scientific knowledge, including chemical processes, the properties of dust and gases, hydrodynamics and magnetohydrodynamics, radiation transfer, and stellar evolution—all of which are covered in this comprehensive work, which will be indispensable for graduate students, seasoned researchers, or even advanced undergrads setting out on the study of planetary evolution.
This book presents the current state of research on disk oscillation theory, focusing on relativistic disks and tidally deformed disks. Since the launch of the Rossi X-ray Timing Explorer (RXTE) in 1996, many high-frequency quasiperiodic oscillations (HFQPOs) have been observed in X-ray binaries. Subsequently, similar quasi-periodic oscillations have been found in such relativistic objects as microquasars, ultra-luminous X-ray sources, and galactic nuclei. One of the most promising explanations of their origin is based on oscillations in relativistic disks, and a new field called discoseismology is currently developing. After reviewing observational aspects, the book presents the basic characteristics of disk oscillations, especially focusing on those in relativistic disks. Relativistic disks are essentially different from Newtonian disks in terms of several basic characteristics of their disk oscillations, including the radial distributions of epicyclic frequencies. In order to understand the basic processes of disk oscillations, studies on binary systems are of importance, as they offer valuable information on wave–wave coupling processes in disk oscillations. Accordingly, some characteristics of oscillations in deformed disks are also presented in this book. The book consists of two parts. Points covered in Part I include, for instance, the basic characteristics of disk oscillations, classification of oscillation modes, and trapping of oscillations. In Part II, the focus is mainly on excitation processes of oscillations, while applications to observations are also discussed.
Accretion Processes in Astrophysics by Ignacio González Martínez-País,Tariq Shahbaz,Jorge Casares Velázquez Pdf
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.
