In particular, the open-close boundary of the magnetic field, so-called the Y-point, can be the new candidate place where magnetic field energy converts into the plasma heat and/or flow energy. Here, we present a new Particle-in-Cell code, which can be applied to the Y-point of the pulsar magnetosphere in axisymmetric geometry. The electromagnetic solver is used in the two-dimensional grid points with the cylindrical coordinate (R, z), while the particle solver operates in ","authors_text":"Mitsuhiro Umizaki, Shinpei Shibata","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-12-18T07:16:11Z","title":"Method of the Particle-in-Cell Simulation for the Y-point in the Pulsar Magnetosphere"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0912.3582","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":"sha256:3fe3be1739b9e27c7711c6f584fc850f8911276cd1fb3f44686369ea553a6687","target":"record","created_at":"2026-05-18T02:10:15Z","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":"d12688b7628dc7451d3f51af51865b38fa7478e9f628b41fe542f56a689308f8","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-12-18T07:16:11Z","title_canon_sha256":"674eaf64e2d6dbd34c0ee422b9dc97a1c0e1e6a4414547512eba243b1a0220d4"},"schema_version":"1.0","source":{"id":"0912.3582","kind":"arxiv","version":1}},"canonical_sha256":"8fa845682333c36e3d426a44d25b6e46d5eb6d2952f3194d4155280769a1b108","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8fa845682333c36e3d426a44d25b6e46d5eb6d2952f3194d4155280769a1b108","first_computed_at":"2026-05-18T02:10:15.738977Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:10:15.738977Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zoOIUO+UEah5zGPhT099x4WM6cXHP1q9Y/kIk/WnVUIEflTNYnzckXUnk7e7EWtAP3TWlPbaQj84P8QOe7i2BA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:10:15.739604Z","signed_message":"canonical_sha256_bytes"},"source_id":"0912.3582","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3fe3be1739b9e27c7711c6f584fc850f8911276cd1fb3f44686369ea553a6687","sha256:7f635d8209104da67073d82209192ac7c3373ad4da36fc3d1a199f570a60a798"],"state_sha256":"1dae8852650a76693a754956458fc2c831aa8035c948630a7c61f9cb95cf6bec"}
