To investigate how macro-scale late-stage infall traverses these gaps, we present multi-epoch, extreme-resolution (R ~ 107,000) PARAS-2 optical spectroscopy of the benchmark Herbig Ae system AB Aurigae. By resolving the kinematics of H-alpha, He I 5876, [O I] 6300, 6363, and Na I D, we map the innermost accretion environment. We find that the [O I] emission is centered near the stellar rest velocity with symmetric","authors_text":"Abhijit Chakraborty, Dipen Sahu, Justyn Campbell-White, Rishikesh Sharma, Shubhendra Nath Das","cross_cats":["astro-ph.EP"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2026-06-17T08:04:17Z","title":"Direct Optical Evidence of Late-Stage Infall in AB Aurigae: A Stagnant [O I] Reservoir and a Crushed Magnetosphere"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.18792","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":"sha256:5315d81b29c8cdbf67108b6bb33b74e7155f6843bdcad76eb568fa12de910ef8","target":"record","created_at":"2026-06-19T16:11:47Z","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":"94296dd9b4e1b9671c23d3990d55570ad6e314772eb986229f33038155460977","cross_cats_sorted":["astro-ph.EP"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2026-06-17T08:04:17Z","title_canon_sha256":"470dd00631f1dbb24b83b887d9ec5176d6f43872b34a04608a04532136a93d44"},"schema_version":"1.0","source":{"id":"2606.18792","kind":"arxiv","version":1}},"canonical_sha256":"c576206844e6f61ce5d0409796eef05cd6927683387831c84dfaf712868677ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c576206844e6f61ce5d0409796eef05cd6927683387831c84dfaf712868677ba","first_computed_at":"2026-06-19T16:11:47.445403Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-19T16:11:47.445403Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hDpp4obfTr9Jn+zMxDI2BWHpvoymIRHHrqN6ZRe/u7k+73Gy+ZrkGByIbMzsx3RsJ0W15XCJaD0r42hQ0DfVBg==","signature_status":"signed_v1","signed_at":"2026-06-19T16:11:47.445758Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.18792","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5315d81b29c8cdbf67108b6bb33b74e7155f6843bdcad76eb568fa12de910ef8","sha256:e3fab5e31c2da1a8d30b9b54df6282bcbc4e31008bff3da2a8af20a55629bd5a"],"state_sha256":"e82987bb087546f6f0fffb3b7eb81179bd803fc2d6cf21b2aa05d6a5df4bf9df"}
