We report the 5 nights of observation on this star in May 2001 during which 1260 high precision radial velocity measurements were obtained. The power spectrum clearly shows several identifiable peaks between 1.7 and 3 mHz. The average large splitting of 105.7 $\\mu$Hz and the amplitude of about 35 cm s$^{-1}$ of these modes are in agreement with theoretical expectations.","authors_text":"Fabien Carrier, Francois Bouchy","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2001-07-05T15:56:08Z","title":"P-mode observations on Alpha Cen A"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0107099","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:bec463c78110bf7176344ad36e5c972c6389ceca50f9653e7e79414661c5faf7","target":"record","created_at":"2026-05-18T01:07:45Z","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":"2e538125f43269200047b68fddacbc61530bf992422c31355975097019ab98a4","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2001-07-05T15:56:08Z","title_canon_sha256":"0af4456a6e3c55da2faf360ad91ce7fe85aee6dc67a71e844a151fe6a05c762e"},"schema_version":"1.0","source":{"id":"astro-ph/0107099","kind":"arxiv","version":1}},"canonical_sha256":"49009462d483b4a6c56f24d2ae094327a4678e106b727d24bd5a5bd0b694f037","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"49009462d483b4a6c56f24d2ae094327a4678e106b727d24bd5a5bd0b694f037","first_computed_at":"2026-05-18T01:07:45.663395Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:07:45.663395Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GFtkEp4uqybvIldTl8sX0bs/FuUi0hIQXU5c3tz5iE+KXNEl242z9+M+z79988QWv3PdGyP0Q4IEiDKKfnH4BA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:07:45.664042Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0107099","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bec463c78110bf7176344ad36e5c972c6389ceca50f9653e7e79414661c5faf7","sha256:be336072c4396b2a07d642f42cfc0d59d4b9cf835a8314f3560195ce6d0729be"],"state_sha256":"94f5cb9b39b86e197dfcac510f45af25cb7b5698167f5cd044e1cffa4e051cc1"}
