The binary star

open access: yesПроект Байкал, 2021
Baroque and classicism were called a binary star. In the national architecture, the avant-garde and neoclassicism can be also called a binary star. The model of succession of styles in architecture does not reflect the real situation in the 1920-1950s ...

Binary Neutron Star Mergers [PDF]

open access: yesLiving Reviews in Relativity, 2012
We review the current status of studies of the coalescence of binary neutron star systems. We begin with a discussion of the formation channels of merging binaries and we discuss the most recent theoretical predictions for merger rates.

The Evolution of Compact Binary Star Systems. [PDF]

open access: yesLiving Rev Relativ, 2014
AbstractWe review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the frequency band of ground-based detectors, while compact binaries of WDs are important sources ...

Search for a Black Hole Binary in Gaia DR3 Astrometric Binary Stars with Spectroscopic Data

open access: yesThe Astrophysical Journal, 2023
We report the discovery of a candidate binary system consisting of a black hole (BH) and a red giant branch star in Gaia DR3. This binary system was discovered from 64,108 binary solutions for which both astrometric and spectroscopic data are available ...

Population of Merging Compact Binaries Inferred Using Gravitational Waves through GWTC-3

open access: yesPhysical Review X, 2023
We report on the population properties of compact binary mergers inferred from gravitational-wave observations of these systems during the first three LIGO-Virgo observing runs.

Nucleosynthesis of Binary-stripped Stars

open access: yesThe Astrophysical Journal, 2023
Abstract The cosmic origin of the elements, the fundamental chemical building blocks of the universe, is still uncertain. Binary interactions play a key role in the evolution of many massive stars, yet their impact on chemical yields is poorly understood.

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet

Statistical Survey for the Physical Characteristic of Near Contact Binary(NCBs) [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2005
The absolute dimensions and orbital elements of 66 near contact binaries, collected from literatures, have been analyzed to investigate the physical characteristics of the near contact binaries as well as co-relations among physical parameters.

Binary stars in Praesepe [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1992
AbstractIn open clusters the scatter about the single-star main sequence is usually negligible. However, unresolved binary systems are brighter and redder than single stars, and thus some ‘stars’ appear shifted away from the main sequence. We make very simple models of the Praesepe cluster, and find evidence that low-mass systems prefer independent ...

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes

open access: yesThe Astrophysical Journal Letters, 2023
Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.
