A large chirality imbalance of electrons inevitably occurs associated with the parity-violating weak process during core collapse of supernovae. We estimate the maximal magnetic field due to this instability to be of order 10^{18} G at the core. This mechanism naturally generates a large magnetic helicity from the chiral asymmetry, which ensures the stability of the large magnetic field.","authors_text":"Akira Ohnishi, Naoki Yamamoto","cross_cats":["hep-ph","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2014-02-19T18:33:29Z","title":"Magnetars and the Chiral Plasma Instabilities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.4760","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":"sha256:7f1628b94d83369c82349f708c8936e01532fb2393eac29ee56f53cba1960280","target":"record","created_at":"2026-05-18T02:58:23Z","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":"bdeabac17c83e9dd7a5e971a5f006359e05b09e2da4d5b0a4f14f69348e8eab2","cross_cats_sorted":["hep-ph","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2014-02-19T18:33:29Z","title_canon_sha256":"8e5353549da3b9d008ced4c8178a7dfc49154ea4bd9358bfc4081ebae2c94c2d"},"schema_version":"1.0","source":{"id":"1402.4760","kind":"arxiv","version":1}},"canonical_sha256":"12679b60f5d66678307043eed9e74004a6ed5ef2de08bc99eb2fcb65279f0752","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"12679b60f5d66678307043eed9e74004a6ed5ef2de08bc99eb2fcb65279f0752","first_computed_at":"2026-05-18T02:58:23.019945Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:58:23.019945Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZDWyNE3Zz6IvmSUbQnAoxzma8k959kBh8F71UVtYgxQdiSNC2sX67NOLmyQtPEN0MQC0F20IU6szwQ03SjxzCA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:58:23.020402Z","signed_message":"canonical_sha256_bytes"},"source_id":"1402.4760","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7f1628b94d83369c82349f708c8936e01532fb2393eac29ee56f53cba1960280","sha256:ffbdf8df586963ee59fb90de45a4f8dc61f4d2a919dc49f7c7e8e7e376c1f5a7"],"state_sha256":"88238ff34928c6ceb0e479693554920662542c3eff8c7a2ccd7d696a6d7ed4a6"}
