A classical approach to handle the anisotropy is based on the double adiabatic approximation assuming that a pressure tensor is well described only by the components parallel and perpendicular to the local magnetic field. This gyrotropic assumption, however, fails around a magnetically neutral region, where the cyclotron period may get comparable to or even longer than a dynamical time in a syst","authors_text":"Kota Hirabayashi, Masahiro Hoshino, Takanobu Amano","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.plasm-ph","submitted_at":"2016-06-26T00:35:34Z","title":"A new framework for magnetohydrodynamic simulations with anisotropic pressure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.07982","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":"sha256:17ed6d7278a980f783658ae821ddbfe65829b14adf86224da2a2b5b8c29a6bf1","target":"record","created_at":"2026-05-18T00:57:12Z","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":"4839801103b341d309a102a60be001819d44cb012ab16330e4e0b9841d4e7d13","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.plasm-ph","submitted_at":"2016-06-26T00:35:34Z","title_canon_sha256":"b532353601c655e1e25b142470d5fbd5305e7cb80520fa334e6a59bfae39197e"},"schema_version":"1.0","source":{"id":"1606.07982","kind":"arxiv","version":1}},"canonical_sha256":"68926c219b1fb55b615d968d578bd696a91b0a1cef30c775972885f4e17037d5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"68926c219b1fb55b615d968d578bd696a91b0a1cef30c775972885f4e17037d5","first_computed_at":"2026-05-18T00:57:12.116273Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:57:12.116273Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LsIYOkATmzMkjYOXK6fpIYtAWRZkfo+xiMNq2u6ab2xRMR4KNX08yKJ9rf3CFwcvnJKfvNhtep2nVEQI778vCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:57:12.116834Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.07982","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:17ed6d7278a980f783658ae821ddbfe65829b14adf86224da2a2b5b8c29a6bf1","sha256:3e7eb9e0513f9eed75b01baac2bbcb023319fde35ccefe6bdcdc271227bf95ab"],"state_sha256":"e0e9e89faf9bf1c195e5e30a0ab268c09a8c1b90993a1772c77a3b3d089e1b2e"}
