Book Description
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.

Book Description
Most stars are formed in binary or multiple systems. Many of these stars will undergo some period of mass transfer at some point during their lifetimes. Hence it is useful to understand the dynamics of mass transfer in binary star systems in order to better understand the current population of stars in the Galaxy and their evolution. A natural class of objects for study are the close binary stars that contain compact objects such as neutron stars or black holes. These systems are bright X-ray emitters, allowing us to study the circumstellar gas within them. We use numerical hydrodynamic modeling to study mass transfer processes in the high-mass X-ray binaries, including the evolutionary sequence between wind fed and disk fed systems, elliptical orbit X-ray binaries, and the global dynamics of LMC X-4 in 3D. We also investigate the properties of high resolution 3D accretion disks, including transport via global wave modes, the effects of tidal stream impact, and the fluid response of tilted disks.

Book Description
A graduate-level textbook on the astrophysics of binary star systems and their evolution Physics of Binary Star Evolution is an up-to-date textbook on the astrophysics and evolution of binary star systems. Theoretical astrophysicists Thomas Tauris and Edward van den Heuvel cover a wide range of phenomena and processes, including mass transfer and ejection, common envelopes, novae and supernovae, X-ray binaries, millisecond radio pulsars, and gravitational wave (GW) sources, and their links to stellar evolution. The authors walk through the observed properties and evolution of different types of binaries, with special emphasis on those containing compact objects (neutron stars, black holes, and white dwarfs). Attention is given to the formation mechanisms of GW sources—merging double neutron stars and black holes as well as ultra-compact GW binaries hosting white dwarfs—and to the progenitors of these sources and how they are observed with radio telescopes, X-ray satellites, and GW detectors (LIGO, Virgo, KAGRA, Einstein Telescope, Cosmic Explorer, and LISA). Supported by illustrations, equations, and exercises, Physics of Binary Star Evolution combines theory and observations to guide readers through the wonders of a field that will play a central role in modern astrophysics for decades to come. 465 equations, 47 tables, and 350+ figures More than 80 exercises (analytical, numerical, and computational) Over 2,500 extensive, up-to-date references
