Population synthesis data of massive binaries: NS/BH-core mergers and double compact objects formation and mergers

Binary population synthesis data generated using the rapid population synthesis code COMPAS. Contains: 1. Full COMPAS output in (.csv format) for running massive binaries varying the common envelope efficiency parameter and the metallicity. 2. Identifying seeds of systems that result in neutron star (NS)/black hole (BH)-core mergers, binary NSs, binary BHs and NS-BH binaries.
