By considering an inhomogeneous mean flow effect on turbulence, it is shown that turbulent cross helicity (velocity--magnetic-field correlation) should enter the expression of turbulent electromotive force as the coupling coefficient for the mean absolute vorticity. The inclusion of the cross-helicity effect makes the present model different from the current $\\alpha$--$\\Omega$-type models mainly in two points. First, in addition to the usual $\\alpha$ (helicity effect) and $\\beta$ (turbulent magnetic diffusivity), we consider the","authors_text":"Dieter Schmitt, Fujihiro Hamba, Nobumitsu Yokoi, Valery Pipin","cross_cats":["physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2016-01-24T06:15:15Z","title":"A new simple dynamo model for stellar activity cycle"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1601.06348","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":"sha256:64515756129b567bf1e842b2503235c6e70c01df74041e713d027803b35606d0","target":"record","created_at":"2026-05-18T01:12:12Z","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":"20a665cec223bcb7917fdfdb3c1aed7f034f7b0413e4f0baec659cf83084626e","cross_cats_sorted":["physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2016-01-24T06:15:15Z","title_canon_sha256":"95f645b05210591a0cb02d72cb1b64e13c55804662f2d94d08d58507256c62a9"},"schema_version":"1.0","source":{"id":"1601.06348","kind":"arxiv","version":2}},"canonical_sha256":"34ed0e36cac4f6ad5a175215a8453f19373045bf5f9050145d22f11c683b02dd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"34ed0e36cac4f6ad5a175215a8453f19373045bf5f9050145d22f11c683b02dd","first_computed_at":"2026-05-18T01:12:12.379438Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:12:12.379438Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iABIVNZTZq7/h+8r+PcXDZlD01q8nzNjPb+xKUXp0bw6VAFYL5fWostWLft38wE4sMCAAxScmawxZcqWxrHRDw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:12:12.379827Z","signed_message":"canonical_sha256_bytes"},"source_id":"1601.06348","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:64515756129b567bf1e842b2503235c6e70c01df74041e713d027803b35606d0","sha256:5a1a77a5703ad7f2d51277bcc17d4f977133dfbcd3b177e32f48634025cc5582"],"state_sha256":"9d593311f2b512aa6611a7362af3675ec5da713294015f64e058bb5d8566882b"}
