We present the core-scale magnetic fields (B-fields) in the near vicinity of the VeLLO L1521F-IRS using submm polarization measurements at 850$~\\mu$m using JCMT POL-2. This is the first attempt to use high-sensitivity observations to map the sub-parsec scale B-fields in a core with a VeLLO. The B-fields are ordered and very well connected to the parsec-scale field geometry seen in our earlier optical polarization observations and the large-sca","authors_text":"Archana Soam, B-G Andersson, Chang Won Lee, Ekta Sharma, Eun Jung Chung, Gwanjeong Kim, Maheswar G., Mika Juvela, Ramprasad Rao, Tie Liu, Woojin Kwon","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2019-08-02T19:09:38Z","title":"First Sub-pc Sale Mapping of Magnetic Fields in the Vicinity of a Very Low Luminosity Object, L1521F-IRS"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.01018","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":"sha256:54c770e1c5bf846c2f6f89bf3003640b03d2e43e4f52a8acba1a1dd0117e13a4","target":"record","created_at":"2026-07-05T00:06:52Z","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":"8d7d6517f3a73892f38f46b905c41707ae743c83c61831f083922a196a4ef9cf","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2019-08-02T19:09:38Z","title_canon_sha256":"849b0311a39dfef96a4f6853b47187da040ffc0926b87955cd4d464aa2d07198"},"schema_version":"1.0","source":{"id":"1908.01018","kind":"arxiv","version":1}},"canonical_sha256":"b63cdf7f889275650db37c51a333bae405ed43066f6471fbac66424c5bdc99d6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b63cdf7f889275650db37c51a333bae405ed43066f6471fbac66424c5bdc99d6","first_computed_at":"2026-07-05T00:06:52.443235Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:06:52.443235Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RS45VjU1vvqrUt6XcBsBKytok596Uro4DTwRro2ZdG4wX9yGXSW0nGMIIK+vzWzkxW7crqtvmpeUpBOyPuZGDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T00:06:52.443611Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.01018","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:54c770e1c5bf846c2f6f89bf3003640b03d2e43e4f52a8acba1a1dd0117e13a4","sha256:f136226bf980d9a162b0cd3f41cdd904a69840cc914cd030531f69ff3b806a07"],"state_sha256":"67d9b48019620418f980eee81ff3178e502190b71409b2d030419e718161b5a7"}
