Notably, a suspected kilonova was identified in its follow-up optical and infrared observations. Here we propose that the origin of GRB 230307A is a neutron star-white dwarf (NS-WD) merger, as this could naturally interpret the long duration and the large physical offset from the center of its host galaxy. In the framework of such a NS-WD merger event, the late-time kilonova-like emission is very likely to be powered by","authors_text":"Jia Ren, Jin-Ping Zhu, Jun Yang, Xiangyu Ivy Wang, Yun-Wei Yu, Ze-Cheng Zou","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2024-02-17T15:06:52Z","title":"What Powered the Kilonova-Like Emission After GRB 230307A in the Framework of a Neutron Star-White Dwarf Merger?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.11304","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":"sha256:93e55636bd9504b8efb57c69cd53a8d330318b388fb5512271dc68efdef90ad6","target":"record","created_at":"2026-07-05T07:56:21Z","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":"30d08e3aba50826384c84b489c04f4f860a2b8ad32529f0d66cad9005f854e70","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2024-02-17T15:06:52Z","title_canon_sha256":"9b7f76c7d0449da180dc89f669f2e2b9a8c5a2bc88eef3ed92eabe1ef345d4df"},"schema_version":"1.0","source":{"id":"2402.11304","kind":"arxiv","version":2}},"canonical_sha256":"51e49544675cfb425533c91ab25d7eb21cca6b48bf36b3122a16386eb7021572","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"51e49544675cfb425533c91ab25d7eb21cca6b48bf36b3122a16386eb7021572","first_computed_at":"2026-07-05T07:56:21.105877Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:56:21.105877Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/Zidbr6lJHWoSyxKWIzUCFAqgx+bkodwTptFOl8lQuw4SeVAQMu5O+2Izv518qP8YZ2rakmli3vC7P5nXERyCA==","signature_status":"signed_v1","signed_at":"2026-07-05T07:56:21.106379Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.11304","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:93e55636bd9504b8efb57c69cd53a8d330318b388fb5512271dc68efdef90ad6","sha256:540f0551da9c26178e418fb81a0012cbeefb2ac7e9831d8e29e4ca5126f27de0"],"state_sha256":"81209d421b4b5846dd5d5eeba4bbf0992f86d795303e69b592514e243bfbf597"}
