International Astronomical Union Colloquium, 1983 Abstract:Ultraviolet and X-ray surveys of the W Ursae Majoris type stars are reviewed. These systems exhibit extended coronas and transition regions that are confined close to the optically determined surfaces. Correlations of X-ray activity with period or rotational velocity indicate a turn-over or saturation of emission at the short periods or high ...

Probing the models: Abundances for high-mass stars in binaries [PDF]
, 2013 The complexity of composite spectra of close binary star system makes study of the spectra of their component stars extremely difficult. For this reason there exists very little information on the photospheric chemical composition of stars in close ...

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.

Where Are the Binary Source Gravitational Microlensing Events? II [PDF]
CNU-A&SS-05/08, 1998 Currently, 6 candidate binary lens events have been reported, while only a single candidate binary source event has been reported. To account for the rarity of binary source events, Dominik pointed out that for a typical binary source event the separation between the component source stars is very large, resulting in large difference in impact ...

Coalescing binary neutron stars [PDF]
Classical and Quantum Gravity, 1999 Coalescing compact binaries with neutron star or black hole components provide the most promising sources of gravitational radiation for detection by the LIGO/VIRGO/GEO/TAMA laser interferometers now under construction. This fact has motivated several different theoretical studies of the inspiral and hydrodynamic merging of compact binaries.

Be Stars as Interacting Binaries [PDF]
Symposium - International Astronomical Union, 1982 At the last IAU Symposium on Be stars held in Bass River, MA in 1975, several of us (including P. Harmanec, M. Plavec, R.S. Polidan, and myself) suggested that Be stars are mass transfer binaries and represent the higher mass counterparts to the familiar Algol systems.

Most EL CVn systems are inner binaries of hierarchical triples [PDF]
, 2020 In spite of their importance for modern astronomy, we do not fully understand how close binary stars containing at least one white dwarf form from main sequence binary stars. The discovery of EL CVn binaries, close pre-white dwarfs with A/F main sequence star companions, offers now the unique possibility to test models of close compact binary star ...

Bimodal Black Hole Mass Distribution and Chirp Masses of Binary Black Hole Mergers
The Astrophysical Journal Letters, 2023 In binary black hole mergers from isolated binary-star evolution, both black holes are from progenitor stars that have lost their hydrogen-rich envelopes by binary mass transfer.

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.
