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 ...

Laboratory analogue of a supersonic accretion column in a binary star system [PDF]

open access: yesNat Commun, 2016
Astrophysical flows exhibit rich behaviour resulting from the interplay of different forms of energy—gravitational, thermal, magnetic and radiative. For magnetic cataclysmic variable stars, material from a late, main sequence star is pulled onto a highly

Star formation environments and the distribution of binary separations [PDF]

open access: bronze, 1998
We have carried out K-band speckle observations of a sample of 114 X-ray selected weak-line T Tauri stars in the nearby Scorpius-Centaurus OB association. We find that for binary T Tauri stars closely associated to the early type stars in Upper Scorpius, the youngest subgroup of the OB association, the peak in the distribution of binary separations is ...

The Evolution of Compact Binary Star Systems [PDF]

open access: yesLiving Reviews in Relativity, 2014
We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are expected to be the most important sources for forthcoming gravitational-wave

Impact of Massive Binary Star and Cosmic Evolution on Gravitational Wave Observations I: Black Hole – Neutron Star Mergers [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
Mergers of black hole-neutron star (BHNS) binaries have now been observed by GW detectors with the recent announcement of GW200105 and GW200115.

Impact of massive binary star and cosmic evolution on gravitational wave observations II: Double compact object rates and properties [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
Making the most of the rapidly increasing population of gravitational-wave detections of BH and NS mergers requires comparing observations with population synthesis predictions. In this work we investigate the combined impact from the key uncertainties

GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral [PDF]

open access: yesPhysical Review Letters, 2017
On August 17, 2017 at 12:41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral.

Multi-messenger Observations of a Binary Neutron Star Merger [PDF]

open access: yesProceedings of Multifrequency Behaviour of High Energy Cosmic Sources - XIII — PoS(MULTIF2019), 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors.

Close Binary Companions to APOGEE DR16 Stars: 20,000 Binary-star Systems Across the Color–Magnitude Diagram [PDF]

open access: yesAstrophysical Journal, 2020
Many problems in contemporary astrophysics—from understanding the formation of black holes to untangling the chemical evolution of galaxies—rely on knowledge about binary stars.

Formation of binary black holes similar to GW190521 with a total mass of ∼150 M⊙ from Population III binary star evolution [PDF]

open access: yes, 2020
In case of zero metal (population III) stars, we show that total mass of binary black holes from binary population III star evolution can be $\sim 150 \,M_{\odot}$, which agrees with mass of a binary black hole, GW190521 recently discovered by LIGO/Virgo.
