They are dense (n_e ~ 10^7 to 10^8 cm^-3), warm (T_e ~ 6000 to 7000 K) and slow moving (~40 km/s) condensations of mostly neutral (H^0) gas. Located within 1000 AU of the central star, they contain heavily CNO-processed material that was ejected from the star about a century ago. Outside the blobs, the inner ejecta include absorption-line clouds with similar conditions, plus emission-line gas that has generally lower densities and a wide","authors_text":"Fred Hamann","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2012-12-13T21:42:37Z","title":"Eta Carinae -- Physics of the Inner Ejecta"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.3348","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":"sha256:6457138dd47323736f2da8391fc2f1500fde75ad2b9761867a408a1e4d1f8f19","target":"record","created_at":"2026-05-18T01:52:38Z","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":"c49724e479133c082800af593959afabc2b4606cd2fc413437ba9e1be6c1f86b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2012-12-13T21:42:37Z","title_canon_sha256":"3aef88cf6606aac69ac1bc7889392e88f1fba0943dd604caa55caf411188bec7"},"schema_version":"1.0","source":{"id":"1212.3348","kind":"arxiv","version":1}},"canonical_sha256":"b03b18f2969efbfc43603b68d992bc2feb382d45a34c4e6d5b9b36a7aa26dfca","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b03b18f2969efbfc43603b68d992bc2feb382d45a34c4e6d5b9b36a7aa26dfca","first_computed_at":"2026-05-18T01:52:38.461800Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:52:38.461800Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uY0507crCdalUSDP6iMDwkXaLMBtEse5g2GcL+06J+aiQVDd9l/h5Tf16DUUgRdPWnV300fhidrv+hQhJOBhBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:52:38.462505Z","signed_message":"canonical_sha256_bytes"},"source_id":"1212.3348","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6457138dd47323736f2da8391fc2f1500fde75ad2b9761867a408a1e4d1f8f19","sha256:8d4113fde0beb93fb324b4f90e86112bd5a6164fa0eccdc55f6c888b765546f9"],"state_sha256":"b62c6e287a4e8b0ecdb1604d13a8444d05877433ec6911540b51ce00aac5079a"}
