Computation of gravitational waves from inspiraling binary neutron stars in quasiequilibrium circular orbits : Formulation and calibration [PDF]

open access: yes, 2001
Gravitational waves from binary neutron stars in quasiequilibrium circular orbits are computed using an approximate method which we propose in this paper. In the first step of this method, we prepare general relativistic irrotational binary neutron stars

Black holes in the low mass gap: Implications for gravitational wave observations [PDF]

open access: yes, 2020
Binary neutron-star mergers will predominantly produce black-hole remnants of mass $\sim 3-4\,M_{\odot}$, thus populating the putative \emph{low mass gap} between neutron stars and stellar-mass black holes.

GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run [PDF]

open access: yes, 2020
We report on gravitational wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between 1 April 2019 15:00 UTC and 1 October 2019 15:00.

Compact Binaries in Star Clusters I - Black Hole Binaries Inside Globular Clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We study the compact binary population in star clusters, focusing on binaries containing black holes, using a self-consistent Monte Carlo treatment of dynamics and full stellar evolution. We find that the black holes experience strong mass segregation and become centrally concentrated.

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 _⊙ .

From a Dinuclear System to Close Binary Cosmic Objects

open access: yesAstronomy, 2023
Applying the ideas from microscopic objects to macroscopic stellar and galactic systems, the evolution of compact di-stars and di-galaxies is studied in the mass asymmetry coordinate. The formation of stable binary systems is analyzed.

Bimodal Black Hole Mass Distribution and Chirp Masses of Binary Black Hole Mergers

open access: yesThe 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.

Which Stars Form Black Holes and Neutron Stars? [PDF]

open access: yes, 2006
I describe the current state of our knowledge of the mapping between the initial masses of stars and the compact objects -- particularly neutron stars and black holes -- that they produce.
