Accretion Disks in Compact Stellar Systems by J. Craig Wheeler Pdf

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.

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.

Accretion Power in Astrophysics by Juhan Frank,A. R. King,Derek Raine Pdf

Accretion Power in Astrophysics examines accretion as a source of energy in both binary star systems containing compact objects, and in active galactic nuclei. Assuming a basic knowledge of physics, the authors describe the physical processes at work in accretion discs and other accretion flows. The first three chapters explain why accretion is a source of energy, and then present the gas dynamics and plasma concepts necessary for astrophysical applications. The next three chapters then develop accretion in stellar systems, including accretion onto compact objects. Further chapters give extensive treatment of accretion in active galactic nuclei, and describe thick accretion discs. A new chapter discusses recently discovered accretion flow solutions. The third edition is greatly expanded and thoroughly updated. New material includes a detailed treatment of disc instabilities, irradiated discs, disc warping, and general accretion flows. The treatment is suitable for advanced undergraduates, graduate students and researchers.

Theory of Accretion Disks 2 by Wolfgang J. Duschl,Juhan Frank,F. Meyer,Emmi Meyer-Hofmeister,Werner M. Tscharnuter Pdf

Accretion disks in astrophysics represent the characteristic flow by which compact bodies accrete mass from their environment. Their intrinsically high luminosity, and recent progress in observational accessibility at all wavelength bands, have led to rapidly growing awareness of their importance and made them the object of intense research on widely different scales, ranging from binary stars to young stellar objects and active galactic nuclei. This book contains the proceedings of the NATO Advanced Workshop on `Theory of Accretion Disks 2' for which some of the most active researchers in the different fields came together at the Max-Planck-Institut for Astrophysics in Garching in March, 1993. Its reviews and contributions give an up-to-date account of the present status of our understanding and provide a stimulating challenge in discussions of open questions in a rapidly developing field.

Physics of Accretion Disks by S Kato Pdf

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 Power in Astrophysics by Juhan Frank,Andrew R. King,Derek J. Raine Pdf

Accretion is recognised as a phenomenon of fundamental importance in astrophysics. Accretion Power in Astrophysics examines accretion as a source of energy in binary star systems containing compact objects and in active galactic nuclei. The authors assume a basic knowledge of physics in order to describe the physical processes at work in accretion discs. The first three chapters explain why accretion is a source of energy, and then present the gas dynamics and plasma concepts necessary for astrophysical applications. The next three chapters then develop accretion in stellar systems, including accretion onto compact objects. Three further chapters give extensive treatment of accretion in active galactic nuclei, and the concluding chapter describes thick accretion discs. The second edition is a complete revision of the earlier account. In particular it gives much greater attention to active galaxies and quasars, where the accretion model is now accepted as the central energy source. The treatment is at a level appropriate for graduate students.

Accretion Processes in Astrophysics by Ignacio Gonzl̀ez Martn̕ez-Pas̕,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.

Theoretical Astrophysics: Volume 2, Stars and Stellar Systems by T. Padmanabhan Pdf

This authoritative textbook - the second volume of a comprehensive three-volume course on theoretical astrophysics - deals with stellar physics. Designed to help graduate students and researchers develop an understanding of the key physical processes governing stars and stellar systems, it teaches the fundamentals, and then builds on them to give the reader an in-depth understanding of advanced topics. The book's modular design allows the chapters to be approached individually, yet seamless transitions create a coherent and connected whole. It can be used alone or in conjunction with Volume I, which covers a wide range of astrophysical processes, and the forthcoming Volume III, on galaxies and cosmology. After reviewing the key observational results and nomenclature used in stellar astronomy, the book develops a solid understanding of central concepts including stellar structure and evolution, the physics of stellar remnants, pulsars, binary stars, the sun and planetary systems, interstellar medium and globular clusters. Throughout, the reader's comprehension is developed and tested with more than seventy-five exercises. This indispensable volume provides graduate students with a self-contained introduction to stellar physics, and will allow them to master the material sufficiently to read and engage in research with heightened understanding.

Astronomy at High Angular Resolution by Henri M. J. Boffin,Gaitee Hussain,Jean-Philippe Berger,Linda Schmidtobreick Pdf

This book offers an essential compendium of astronomical high-resolution techniques. Recent years have seen considerable developments in such techniques, which are critical to advances in many areas of astronomy. As reflected in the book, these techniques can be divided into direct methods, interferometry, and reconstruction methods, and can be applied to a huge variety of astrophysical systems, ranging from planets, single stars and binaries to active galactic nuclei, providing angular resolution in the micro- to tens of milliarcsecond scales. Written by experts in their fields, the chapters cover adaptive optics, aperture masking imaging, spectra disentangling, interferometry, lucky imaging, Roche tomography, imaging with interferometry, interferometry of AGN, AGN reverberation mapping, Doppler- and magnetic imaging of stellar surfaces, Doppler tomography, eclipse mapping, Stokes imaging, and stellar tomography. This book is intended to enable a next generation of astronomers to apply high-resolution techniques. It informs readers on how to achieve the best angular resolution in the visible and near-infrared regimes from diffraction-limited to micro-arcsecond scales.
