In this theory, a black hole can carry a vector hair, making the metric deviate from the Schwarzschild metric. To investigate the detectability of the vector hair, we consider an Extreme Mass Ratio Inspiral (EMRI) system, where a stellar-mass black hole inspiraling into a supermassive black hole. We find that, with a one-year observation of an EMRI by a space-based gravitational-wave detector, we can probe the vector charge as small as $Q\\sim 10^{-3}$ in the ","authors_text":"Dicong Liang, Lijing Shao, Rui Xu, Zhan-Feng Mai","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2022-12-19T10:23:37Z","title":"Probing vector hair of black holes with extreme mass ratio inspirals"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.09346","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":"sha256:17eef6e7545a8e015ba8a91f6da6ca20e12b5a867e4d9006e50a73b5b44c4a02","target":"record","created_at":"2026-07-05T05:44:51Z","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":"7ff88a2c256db88df69791a6f71b04b8292582c4932ae8c2df1a0e2b8eca8e6a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2022-12-19T10:23:37Z","title_canon_sha256":"61135cf013b57c7f2d4d156e3752d69939e7cae75dacbf59411c676e71fb90ec"},"schema_version":"1.0","source":{"id":"2212.09346","kind":"arxiv","version":2}},"canonical_sha256":"bbd813f9e0d6409047c147a4fc0a1d9371c532f4836e033abf7913e7b59eceba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bbd813f9e0d6409047c147a4fc0a1d9371c532f4836e033abf7913e7b59eceba","first_computed_at":"2026-07-05T05:44:51.944320Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:44:51.944320Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fpyRcug5g5FfntrblkCqUUXXHx2ttsdT0jYlAW2ROLmTHy2YUQUokoZIHvG+XDp16BovTKPi/TxhtTXs3XRuCA==","signature_status":"signed_v1","signed_at":"2026-07-05T05:44:51.944778Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.09346","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:17eef6e7545a8e015ba8a91f6da6ca20e12b5a867e4d9006e50a73b5b44c4a02","sha256:adf4abb14754f3dc08f9c6edf2220baffa9f43a2aafe8618ddff7405e2ab4d70"],"state_sha256":"0069797ef183bd6c89efd6b84339df3a32fc8332eb0b792d09f7fbf501e8bad2"}
