Binary Neutron Star Mergers [PDF]

open access: yesLiving Reviews in Relativity, 2012
AbstractWe 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. Next, we turn to the quasi-equilibrium formalisms that are used to study binaries prior to the merger phase ...

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.

The Evolution of Compact Binary Star Systems

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

The Evolution of Compact Binary Star Systems

open access: yesLiving Reviews in Relativity, 2006
We 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 ...

V1507 CYGNI (HD187399): A Highly Evolved, Enigmatic Interacting Binary System with an Eccentric Orbit

open access: yesThe Astronomical Journal, 2023
The properties of the interacting, eccentric orbit binary V1507 Cyg (HD187399) are examined with spectra that cover wavelengths from 0.63–0.68 μ m. The spectrum of the brightest star is similar to that of the B8 I star β Ori, although with absorption ...

Binary post-AGB stars [PDF]

open access: yesSymposium - International Astronomical Union, 1997
Low and intermediate mass stars leave the Asymptotic Giant Branch (AGB) when the mass in their H-rich envelope is less than about 0.01 M⊙, and the high mass loss drops several orders of magnitude. The central star rapidly evolves to the left part of the HR diagram along a track of constant luminosity (e.g. Schönberner 1983).

NY Bootes: An Active Deep and Low-mass-ratio Contact Binary with a Cool Companion in a Hierarchical Triple System

open access: yesThe Astrophysical Journal, 2023
The first detailed photometric and spectroscopic study of G-type short-period binary NY Boo is presented. The radial velocity curve was obtained by the cross-correlation function (CCF) method based on LAMOST and SDSS spectra, which derived its mass ratio

Binary Star [PDF]

open access: yesProceedings of the 52nd Annual IEEE/ACM International Symposium on Microarchitecture, 2019
As memory capacity scales, traditional cache and memory hierarchy designs are facing increasingly difficult challenges in ensuring high reliability with low storage and performance cost. Recent developments in 3D die-stacked DRAM caches and nonvolatile memories (NVRAMs) introduce promising opportunities in tackling the reliability, performance, and ...

POSYDON: A General-purpose Population Synthesis Code with Detailed Binary-evolution Simulations

open access: yesThe Astrophysical Journal Supplement Series, 2023
Most massive stars are members of a binary or a higher-order stellar system, where the presence of a binary companion can decisively alter their evolution via binary interactions. Interacting binaries are also important astrophysical laboratories for the

Born to Be Wide: The Distribution of Wide Binaries in the Field and Soft Binaries in Clusters

open access: yesThe Astrophysical Journal, 2023
Most stars, binaries, and higher-multiplicity systems are thought to form in stellar clusters and associations that later dissociate. Very wide binaries can be easily disrupted in clusters due to dynamical evaporation (soft binaries) and/or tidal ...
