COMPAS rapid binary population synthesis code

Compact Object Mergers: Population Astrophysics & Statistics

COMPAS is a publicly available rapid binary population synthesis code (https://compas.science/) that is developed for easily adjustable evolution prescriptions and model parameters. COMPAS draws binary properties from a set of initial distributions, and evolves a binary star from zero-age main sequence to the end of its life as two compact remnants. It has been used for inference from observations of gravitational wave mergers, Galactic double neutron stars, and radio pulsars.
