The 3-D MHD Anelastic Spherical Harmonic code, using slope-limited diffusion, is employed to capture convection and dynamo processes in such a young sun. The simulation is carried out in a spherical shell that encompasses 3.8 density scale heights of the solar convection zone. We find that dynamo action with a high degree of time variation occurs, with many periodic polarity reversals every 6.2 years. The magnetic energy also rises and falls with a regular period, with t","authors_text":"Allan Sacha Brun, Juri Toomre, Kyle Augustson, Mark Steven Miesch","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2013-10-31T07:54:44Z","title":"Cycling Dynamo in a Young Sun: Grand Minima and Equatorward Propagation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1310.8417","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:f25de5003916ff1bf42b309e1046f19bf532a4cb40cfd374974fcdf6df6ffc23","target":"record","created_at":"2026-05-18T03:08:17Z","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":"6ebb8c9136d965e75c618529306981eeac9cd17ae8db7dfe6fa731157d0df1bd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2013-10-31T07:54:44Z","title_canon_sha256":"232af4dd3d74242a17e05546aabe4802e4eb075349a953779714c9d538b65592"},"schema_version":"1.0","source":{"id":"1310.8417","kind":"arxiv","version":1}},"canonical_sha256":"08ccebf47842f7a6edb01b0323e53c4d47ec403906f2d737e4ddbcaa27e5aa5f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"08ccebf47842f7a6edb01b0323e53c4d47ec403906f2d737e4ddbcaa27e5aa5f","first_computed_at":"2026-05-18T03:08:17.126233Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:08:17.126233Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xQYZMsgMPUM//+UjAz3wtNlI/VR5oreTlOjpp2ukIkmPlNHzamYZzvYdlo7KeLoIH0nBCyIJS2faZau4zkQrDA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:08:17.126885Z","signed_message":"canonical_sha256_bytes"},"source_id":"1310.8417","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f25de5003916ff1bf42b309e1046f19bf532a4cb40cfd374974fcdf6df6ffc23","sha256:fe4f003a96c5e953da3b9300461d66a5d1f52e2669a79739bba91a29b4af7b56"],"state_sha256":"1537a336dd2afd235316340c61ffbc770744ff44ec1f53324aab1b725c9ed0d7"}
