New data from 2010 August, combined with three archival data sets from as early as 1999 December, provide a baseline of 3886 days (more than 10 1/2 years) to perform the measurement. Correlating the four positions of RX J0822-4300 measured in each data set implies a projected proper motion of mu 71 \\pm 12 masy. For a distance of 2 kpc this proper motion is equivalent to a recoil velocity of 672 \\pm 115 ","authors_text":"P.Frank Winkler, Robert Petre, Tobias Prinz, Werner Becker","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2012-04-16T15:07:54Z","title":"The Proper Motion of the Central Compact Object RX J0822-4300 in the Supernova Remnant Puppis A"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1204.3510","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":"sha256:047573735fe5ac5f16dbc4475a1784ac3e703840a8513f3467038a060da91447","target":"record","created_at":"2026-05-18T01:57:52Z","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":"2fa4763e511dbd654704f57d3832fb400c6cf731a86589484404015538a3ce49","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2012-04-16T15:07:54Z","title_canon_sha256":"0a3b9dc457bbf19be74cdfc84abf840404e409ddad795758dbfeefdfe9f2f1b7"},"schema_version":"1.0","source":{"id":"1204.3510","kind":"arxiv","version":2}},"canonical_sha256":"072a022a4fa5eb684a0621d1f098084ca486345cd2323a135baed84c9ac3b2cd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"072a022a4fa5eb684a0621d1f098084ca486345cd2323a135baed84c9ac3b2cd","first_computed_at":"2026-05-18T01:57:52.004301Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:57:52.004301Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"D9P5Z5Bpoolad93Bxh0friCsr+Xa30UMzOY3URyOf4OBAe1Uu98fjSxND6fsMvgS0D1vZD2C+fXDbydkhYixBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:57:52.004874Z","signed_message":"canonical_sha256_bytes"},"source_id":"1204.3510","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:047573735fe5ac5f16dbc4475a1784ac3e703840a8513f3467038a060da91447","sha256:c7d1887907097c991eb7a4a6d16f15fed880b7b15fe7306a95985c57e7bd2cc6"],"state_sha256":"da74dd33835532fc607c32533be5f85dbb91f95d04e5268a88cb4fee01d72e34"}
