Classification of close binary stars using recurrence networks [PDF]

Chaos, 2019
Close binary stars are binary stars where the component stars are close enough such that they can exchange mass and/or energy. They are subdivided into semidetached, overcontact, or ellipsoidal binary stars. A challenging problem in the context of close binary stars is their classification into these subclasses based solely on their light curves ...

Microlensing of close binary stars [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
The gravity due to a multiple-mass system has a remarkable gravitational effect: the extreme magnification of background light sources along extended so-called caustic lines. This property has been the channel for some remarkable astrophysical discoveries over the past decade, including the detection and characterisation of extra-solar planets, the ...

Instabilities in Close Neutron Star Binaries

Physical Review Letters, 1995
We 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

CLOSE-IN STELLAR COMPANIONS IN CLOSE BINARY STARS

Publications of the Korean Astronomical Society, 2015
Close binary stars are so close that one component has an effect on the evolution of the other. But how do they form and evolve? This is an unsolved problem. One speculation is that the binary is a part of a hierarchical triple and its orbit shrinks due to interaction with the third component.

Close binary 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 ...

The evolution of close binary stars

Astronomy Reports, 2016
A 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 ...
