This late-time brightening is unexpected from the kilonova model or the off-axis top-hat jet model for gamma-ray burst afterglows. In this paper, by assuming that the merger remnant is a long-lived NS, we propose that the interaction between an electron-positron-pair ($e^+e^-$) wind from the central NS and the jet could produce a long-lived reverse shock, from which a new emission componen","authors_text":"Bing Li, Jin-Jun Geng, Long-Biao Li, Xue-Feng Wu, Yan-Zhi Meng, Yong-Feng Huang, Zi-Gao Dai","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-03-20T02:06:01Z","title":"Brightening X-ray/Optical/Radio Emission of GW170817/SGRB 170817A: Results of an Electron-Positron Wind from the Central Engine?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.07219","kind":"arxiv","version":1},"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":"sha256:47df055735b9f651cb8e3b5aa5ed1b52468864068684f611def3452a537449b3","target":"record","created_at":"2026-05-18T00:19:46Z","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":"106e6df8558673cd181ea704782e9f4d3b4f432b0fc0e9cc0167e9daaa8cf4d6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-03-20T02:06:01Z","title_canon_sha256":"e17e3e5a78d04fc6af13b76d2ea56fa557d1d971d5bf1ee99bf022bbf1299a39"},"schema_version":"1.0","source":{"id":"1803.07219","kind":"arxiv","version":1}},"canonical_sha256":"f8704c5d8a53626c72fd24aa0e364c6316041fc96ff524bad733f1c1bc16b770","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f8704c5d8a53626c72fd24aa0e364c6316041fc96ff524bad733f1c1bc16b770","first_computed_at":"2026-05-18T00:19:46.908762Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:19:46.908762Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rFePsQ9OrKWGjQTECAmJ3lBBtCbMqMy6s/NPff0TuH0SvopDFlJAmOZZ2etm6duNlAwH4PHRX4wOX00KciVLAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:19:46.909458Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.07219","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:47df055735b9f651cb8e3b5aa5ed1b52468864068684f611def3452a537449b3","sha256:2713cf488945638f1a3f4751224f9d2e3f085652ff480e8b3c9ebc0e365c5c52"],"state_sha256":"a1a7f43cf386c0224ff88f1fe6691d7b810860a692058a1d7497b56247021e06"}
