These mergers result in a remnant black hole, possibly surrounded by an accretion disk. The mass and spin of the remnant black hole depend on the properties of the coalescing binary. We construct a map from the binary components to the remnant black hole using a sample of numerical-relativity simulations of different mass ratios $q$, (anti-)aligned dimensionless spins of the black hole $a_{\\rm BH}$","authors_text":"Francesco Pannarale, Francesco Zappa, Michela Mapelli, Nicola Giacobbo, Sebastiano Bernuzzi","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2019-03-27T18:02:25Z","title":"Black-hole remnants from black-hole--neutron-star mergers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.11622","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:967646df683e22135d5737098ea0f7f6bdbfb5abc9a1118345c85d3f6c56b0e1","target":"record","created_at":"2026-07-05T00:37:16Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"b481bb636a823fbb0a974602bde10b7ac134b5004a691ed6d4ef19c89e09a8d5","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2019-03-27T18:02:25Z","title_canon_sha256":"8ef0b183fc3dd7c9efb86ca8ac1e7fba2289230af4e5a69e8239c58e676c9f91"},"schema_version":"1.0","source":{"id":"1903.11622","kind":"arxiv","version":2}},"canonical_sha256":"82bec1e0ce4ef2f05d3eb41b2b8d156d04cd028c815bd9cec2922010344151d6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"82bec1e0ce4ef2f05d3eb41b2b8d156d04cd028c815bd9cec2922010344151d6","first_computed_at":"2026-07-05T00:37:16.461801Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:37:16.461801Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9K5eqSoUXzQJ+SHvli45Fa4HXxjD6m9Vgyq3HEwKEDWNAjRYMOYEHAqyQ7ygu/SOqUoNXZHZVwTk9E/TrFWcCA==","signature_status":"signed_v1","signed_at":"2026-07-05T00:37:16.462230Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.11622","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:967646df683e22135d5737098ea0f7f6bdbfb5abc9a1118345c85d3f6c56b0e1","sha256:997455ddab64afe84943f9bb6b16d925f78ea41214c0792604d3c29b966078f9"],"state_sha256":"1762cc585b6a3fb64ee3675b77ed07aba82e344bed26d9c490964354ce4bda0d"}
