COMMISSION 42: CLOSE BINARY STARS [PDF]

Proceedings of the International Astronomical Union, 2008
Two meetings of interest to close binaries took place during the reporting period: A full day session on short-period binary stars – mostly CV's – (Miloneet al. 2008) during the 2006 AAS Spring meeting in Calgary and the very broadly designed IAU Symposium No.

High-velocity stars from the interaction of a globular cluster and a massive black hole binary [PDF]

, 2016
High-velocity stars are usually thought to be the dynamical product of the interaction of binary systems with supermassive black holes. In this paper, we investigate a particular mechanism of production of high-velocity stars as due to the close ...

Irrotational binary neutron stars in quasiequilibrium [PDF]

, 1999
We report on numerical results from an independent formalism to describe the quasi-equilibrium structure of nonsynchronous binary neutron stars in general relativity.

Computation of gravitational waves from inspiraling binary neutron stars in quasiequilibrium circular orbits : Formulation and calibration [PDF]

, 2001
Gravitational waves from binary neutron stars in quasiequilibrium circular orbits are computed using an approximate method which we propose in this paper. In the first step of this method, we prepare general relativistic irrotational binary neutron stars

Super slowly spinning stars in close binaries

Monthly Notices of the Royal Astronomical Society: Letters, 2023
ABSTRACT Stars in short-period binaries typically have spins that are aligned and synchronized with the orbit of their companion. In triple systems, however, the combination of spin and orbital precession can cause the star’s rotation to evolve to a highly misaligned and sub-synchronous equilibrium known as a Cassini state. We identify a

Surveying Planetary Nebulae Central Stars for Close Binaries: Constraining Evolution of Central Stars Based on Binary Parameters

Galaxies, 2018
The increase in discovered close binary central stars of planetary nebulae is leading to a sufficiently large sample to begin to make broader conclusions about the effect of close binary stars on common envelope evolution and planetary nebula formation ...

Close encounters of star–black hole binaries with single stars

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Multibody dynamical interactions of binaries with other objects are one of the main driving mechanisms for the evolution of star clusters. It is thus important to bring our understanding of three-body interactions beyond the commonly employed point-particle approximation.

CLOSE BINARY SYSTEMS ON LATE EVOLUTIONARY STAGES

Odessa Astronomical Publications, 2017
Observational and theoretical progress in investigations of close binary stars allow to understand the nature and evolution of many types of close binary systems containing peculiar components: Wolf-Rayet stars, white dwarfs neutron stars and black holes.

Close encounters in young stellar clusters: implications for planetary systems in the solar neighbourhood [PDF]

, 2007
The stars that populate the solar neighbourhood were formed in stellar clusters. Through N-body simulations of these clusters, we measure the rate of close encounters between stars. By monitoring the interaction histories of each star, we investigate the
