Understanding how a magneto-rotational-instability (MRI)-active disk connects to a protostar's surface remains a significant challenge. To investigate the mechanisms of mass and angular momentum transfer, we develop a global, three-dimensional magnetohydrodynamic model of boundary layer accretion around a magnetized, convective low-mass protostar. Our results reveal that angular momentum transport mechanisms transition significant","authors_text":"Kazunari Iwasaki, Kengo Tomida, Shinsuke Takasao, Takashi Hosokawa","cross_cats":["astro-ph.EP","astro-ph.HE"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2025-03-19T15:48:30Z","title":"Connecting a Magnetized Disk to a Convective Low-mass Protostar: A Global Three-dimensional Model of Boundary Layer Accretion"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.15350","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:e06247d20a0d74826f512c0773807fe93a6632929b04893a505b386a5c21d5cb","target":"record","created_at":"2026-07-05T10:35:24Z","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":"fecf9300bef78894556884cec237cfd93f7676f682ccd9aceceaaacb4fb1c50c","cross_cats_sorted":["astro-ph.EP","astro-ph.HE"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2025-03-19T15:48:30Z","title_canon_sha256":"991712052364249612e865420315951d6b6a7125ccfa8d0c504a09475bcabb4e"},"schema_version":"1.0","source":{"id":"2503.15350","kind":"arxiv","version":1}},"canonical_sha256":"743b1399001165f1fa2815f4d0ed0fa7e3891250189f0451ff5182ac66b0202f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"743b1399001165f1fa2815f4d0ed0fa7e3891250189f0451ff5182ac66b0202f","first_computed_at":"2026-07-05T10:35:24.745080Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:35:24.745080Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pCtQ0ShwBRLrHLIVX2AW4XQQwytFTsub5FvhTbtKFi+ggDs3wAiY3JbUEIGwvQgqJPntSYe2esa1Ih8NJBXODQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:35:24.745707Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.15350","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e06247d20a0d74826f512c0773807fe93a6632929b04893a505b386a5c21d5cb","sha256:c67d3ffcecb1d3e278ba243672faa1b15d575600d4274709162296de92170fd4"],"state_sha256":"94accca1ba342dc87a620dd0b9b6add341f71cb98edc10062b413bbae1bc99a1"}
