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 ...

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

The ELM Survey South. II. Two Dozen New Low-mass White Dwarf Binaries

open access: yesThe Astrophysical Journal, 2023
We present the results from our ongoing spectroscopic survey targeting low-mass white dwarf binaries, focusing on the southern sky. We used a Gaia DR2- and eDR3-based selection and identified 28 new binaries, including 19 new extremely low-mass (ELM ...

The evolution of massive binary systems [PDF]

open access: yesSerbian Astronomical Journal, 2020
The evolution of massive stars in close binary systems is significantly different from single star evolution due to a series of interactions between the two stellar components.

White Dwarfs Revealed in Gaia’s Candidate Compact Object Binaries

open access: yesThe Astrophysical Journal, 2023
Discovery and characterization of black holes (BHs), neutron stars (NSs), and white dwarfs (WDs) with detached luminous companions (LCs) in wide orbits are exciting because they are important test beds for dark remnant (DR) formation physics as well as ...

Post-merger Gravitational-wave Signal from Neutron-star Binaries: A New Look at an Old Problem

open access: yesThe Astrophysical Journal, 2023
The spectral properties of the post-merger gravitational-wave signal from a binary of neutron stars encodes a variety of information about the features of the system and of the equation of state describing matter around and above nuclear saturation ...

GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo during the Second Part of the Third Observing Run

open access: yesPhysical Review X, 2023
The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with Advanced LIGO and Advanced Virgo up to the end of their third observing run.

Dark stars and gravitational waves: Topical review

open access: yesResults in Physics, 2023
Motivated by recent observations of compact binary gravitational wave events reported by LIGO/Virgo/KAGRA, we review the basics of dark and hybrid stars11 In this review “hybrid stars” means “dark-matter admixed stars”, though this term usually refers to

PSR J1953+1844 Probably Being the Descendant of an Ultracompact X-Ray Binary

open access: yesThe Astrophysical Journal Letters, 2023
PSR J1953+1844 (i.e., M71E) is a millisecond pulsar in a 53 minute binary orbit discovered by the Five-hundred-meter Aperture Spherical radio Telescope. The mass function from pulsar timing is 2.3 × 10 ^−7 M _⊙ .
