Gravitational-wave detectors are starting to reveal the redshift evolution of the binary black
hole (BBH) merger rate, R BBH (z). We make predictions for R BBH (z) as a function of black …

Abstract Compact Object Mergers: Population Astrophysics and Statistics (COMPAS;
https://compas. science) is a public rapid binary population synthesis code. COMPAS …

Mergers of black hole–neutron star (BHNS) binaries have now been observed by
gravitational wave (GW) detectors with the recent announcement of GW200105 and …

Common-envelope (CE) evolution in massive binary systems is thought to be one of the
most promising channels for the formation of compact binary mergers. In the case of merging …

We perform 3D hydrodynamical simulations of a common-envelope event involving a 12 red
supergiant donor. Massive stars are expected to be qualitatively different from low-mass …

Rapid binary population synthesis codes are often used to investigate the evolution of
compact-object binaries. They typically rely on analytical fits of single-star evolutionary …

Circumbinary disks are found in a variety of astrophysical scenarios, spanning binary star
formation to accreting supermassive black hole binaries. Depending on the characteristics of …

Common envelope (CE) evolution is an outstanding open problem in stellar evolution,
critical to the formation of compact binaries including gravitational-wave sources. In the" …

Binaries comprised of a neutron star (NS) and a black hole (BH) have so far eluded
observations as pulsars and with gravitational waves (GWs). We model the formation and …

Abstract Massive stars (∼ 8–25 M⊙) stripped of their hydrogen-rich envelopes via binary
interaction are thought to be the main progenitors for merging neutron stars and stripped …
