The close pair of M-type dwarfs Ba,Bb with a tentative period of 3.7 days moves around the main component A on a 26-year orbit. The mass of the \"dark companion\" Ba+Bb is comparable to the mass of A, causing large motion of the photo-center. The combined spectro-interferometric orbit of AB is derived and the relative photometry of the components A and B is given. A weak signature of Ba and Bb is detected in the high-resolution spectra by cross-correlation and by variable emission in the Bahlmer hydrogen line","authors_text":"Andrei Tokovinin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2013-01-07T21:30:33Z","title":"Kappa Fornaci, a triple radio-star"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.1352","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":"sha256:0fe03836ce60e6c8db36cd2a03cab3aabb64d8418d7159684c522bb0dc30d365","target":"record","created_at":"2026-05-18T01:52:20Z","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":"883665101aa08e3e34a18af675d4d5bd55a95a43a4691ba3ce8ab9e03d4d90bb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2013-01-07T21:30:33Z","title_canon_sha256":"b4a30d5cca16f640e5678ec0145be45750f91fb2c18ccb4a33b7fdb0c5c8142f"},"schema_version":"1.0","source":{"id":"1301.1352","kind":"arxiv","version":1}},"canonical_sha256":"16a9a23648889be5a6302515d793ffea33f3d8ad3139d6eb7ddc6b01c502939e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"16a9a23648889be5a6302515d793ffea33f3d8ad3139d6eb7ddc6b01c502939e","first_computed_at":"2026-05-18T01:52:20.860393Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:52:20.860393Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"cGbptXLPeJB3W7+AmpLCROPjZDsoyZd2U8SwH2T5bUPmwoCuNhxmTosWc1k2xFnfDXbbRI1xRjJXMSiUAQnLAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:52:20.860788Z","signed_message":"canonical_sha256_bytes"},"source_id":"1301.1352","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0fe03836ce60e6c8db36cd2a03cab3aabb64d8418d7159684c522bb0dc30d365","sha256:66ca593989609fce4d59068a037b1dd4ce07618eb98b2ca99a3327f33325313c"],"state_sha256":"ef5763eeedd0fdfd9bf684a6e62853bb930e1067722ffb3136eef8fd723d6a58"}
