Disks in close binaries offer great opportunities for testing and refining astrophysical models and are studied in this thesis in the context of dwarf novae and planet formation. Dwarf novae are a subclass of cataclysmic variables (CVs), which are close binary systems with separations on the order of one solar radius, consisting of a white dwarf ...

Evolution of close binary stars: theory and observations
Physics Uspekhi, 2019We review modern concepts in the physics and evolution of close binary stars. The review is based, on the one hand, on numerical simulations of the evolution of their components and the processes that accompany that evolution and, on the other hand, on ...

Instabilities in Close Neutron Star Binaries
Physical Review Letters, 1995We report on a new analysis of instabilities in close neutron star binaries based upon (3+1) dimensional general relativistic numerical hydrodynamics calculations. When a realistic equation of state is employed, orbit calculations for two 1.45{ital M}{sub {circle_dot}} neutron stars reveal surprising evidence that general relativistic effects may cause

At the time of this report in September 1993, about a year before the next General Assembly in 1994, the membership of Commission 42 stands at 357, an increase of forty-two members since the time of the last report prepared in September 1990. This is an increase of more than 10 percent, indicating the continuing vitality of our Commission in ...

The evolution of close binary stars
Astronomy Reports, 2016A review of our current understanding of the physics and evolution of close binary stars with various masses under the influence of the nuclear evolution of their components and their magnetic stellar winds is presented. The role of gravitational-wave radiation by close binaries on their evolution and the loss of their orbital angular momentum is also ...

Research on close binary systems has continued at a high level during the past triennium, although the rate of growth is noticeably slower - probably reflecting the cutbacks in funds to which many of us are subject. There have also been changes of emphasis within the field, which are commented on in the pages that follow.

Interest in close binary stars continues to grow apace. Substantial fractions of the observing time on the International Ultraviolet Explorer and the various X-ray satellites have been devoted to extending our knowledge of a variety of interacting binaries. These, together with applications of novel ground-based techniques and the steady improvement of
