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 ...

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

Rotation in Close Binary Stars
Highlights of Astronomy, 1980In binary stars of short period, axial rotation of the components tends to be synchronized with the orbital revolution. Rotation of B. and A stars is therefore slowed down, while for the later-type stars, it is accelerated. This latter fact probably contributes to the phenomenon of the RS CVn stars.

1994
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 ...

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.

Late-Type Stars and Close Binaries
2007Late-type stars are generally characterized by the chromospheric structure showing active phenomena observable by the formation of emission lines and emission of X-ray and UV radiations. In the optical region, most ubiquitous emission lines are CaII H, K lines, while Hα line appears in fully developed chromospheres.

Close-Binary Stars in Planetary Nebulae
2019It is now clear, after many years of heated debate, that a significant fraction of planetary nebulae are the product of close-binary evolution. In this chapter, we present the history of the field and some of the obstacles that have hindered progress - including detailed descriptions of the techniques employed and their limitations.

Periods and Eccentricities of Close Binary Stars
Nature, 1949EXAMINATION of the material in the Fifth Lick Catalogue of spectroscopic binaries, recently published by Moore and Neubauer1, reveals a definite relation between periods of revolution P and eccentricities of orbits e for binaries with short periods if their components belong to the main sequence of stars.

Highly evolved close binary stars
Space Science Reviews, 1995Recent progress on observational and theoretical investigations of close binary systems of stars allows one to understand the origin and evolution of peculiar objects in close binary systems: Wolf-Rayet stars, white dwarfs, neutron stars and black holes.
