Understanding how massive stars assemble their mass is a major astrophysical challenge, primarily because the critical accretion, ejection, and fragmentation processes occurring within the innermost 100 au remain largely inaccessible. Current facilities, such as ALMA and near-infrared interferometers, either lack the resolution to probe the compact high-mass star-disk interaction zone or are severely hindered by high extinction and marginal sp","authors_text":"Alvaro Sanchez-Monge, Emma Bordier, Evgenia Koumpia, Jean-Philippe Berger, Joel Sanchez-Bermudez, Lucas Labadie","cross_cats":["astro-ph.SR"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-06-16T17:12:02Z","title":"Resolving the smallest scales of massive star formation: A case for next-generation thermal-infrared interferometers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.18178","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":"sha256:4d04c6639b0c1d400f9d2cacdc8e08f6b66ae929804b0f568996c9078f85de92","target":"record","created_at":"2026-06-19T16:10:50Z","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":"dc8ad2a1c66d31a8a4148cc439b02417a21c03de25316f2f6b7b0a58208b0b5d","cross_cats_sorted":["astro-ph.SR"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-06-16T17:12:02Z","title_canon_sha256":"925eaa60463fd13676fe033101febe698aeec7f035c0bba29567410596930089"},"schema_version":"1.0","source":{"id":"2606.18178","kind":"arxiv","version":1}},"canonical_sha256":"356a0aca19d388211bff8d396b7b8137a0b015b1f93dcb00cd5bb8eda1fe9982","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"356a0aca19d388211bff8d396b7b8137a0b015b1f93dcb00cd5bb8eda1fe9982","first_computed_at":"2026-06-19T16:10:50.347841Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-19T16:10:50.347841Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6l43ui451tParlWoCVfDiuWhH8Z/V89kD5f64U1k7VFVOJ+gfP4MAC3KNGLB+Hs4s+mpCXuKwFPYLJZ9bDdDDw==","signature_status":"signed_v1","signed_at":"2026-06-19T16:10:50.348183Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.18178","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4d04c6639b0c1d400f9d2cacdc8e08f6b66ae929804b0f568996c9078f85de92","sha256:dd0f4877063fc018705981af5159f1f934e50da64a0abed519e90560e7c17d0c"],"state_sha256":"b0e47a779f3d008b8cf275f262c0f447e9a48674bc027976ec974a09237ad4d8"}
