However, it remains uncertain whether the sublimation of SO$_2$ surface frost or volcanic outgassing is the primary source of the SO$_2$ atmosphere. In this study, we produce a 2D model of Io's SO$_2$ atmosphere using the Direct Simulation Monte Carlo (DSMC) method. For this purpose, we conduct a literature review on thermophysical parameters of Io's SO$_2$ surface frost to refine the surface temperature model in accordance with the most recent o","authors_text":"Audrey Vorburger, Leander Schlarmann, Nicolas Thomas, Peter Wurz, Tim Mosimann","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.EP","submitted_at":"2026-06-17T13:16:06Z","title":"Interactions of sublimated frost with volcanic plumes: Modelling Io's SO$_2$ atmosphere using the DSMC method"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.19048","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":"sha256:6a7fa2aa446fa3081ef9509765b974e13974131b58eec4a44cb0994e64139e9c","target":"record","created_at":"2026-06-19T16:11:55Z","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":"110a2933ab3764eb241336662f9b32c2702e03ed70d6ee8974fd60ff41d97ef2","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.EP","submitted_at":"2026-06-17T13:16:06Z","title_canon_sha256":"8aa46f0a57c0adb44a0b83dee7a400c141e5501baf9556658f64f9a9fd54dcef"},"schema_version":"1.0","source":{"id":"2606.19048","kind":"arxiv","version":1}},"canonical_sha256":"538967828de7863bf4d08c7bf840e65627add2fc84f469a2d99c49b184a45d99","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"538967828de7863bf4d08c7bf840e65627add2fc84f469a2d99c49b184a45d99","first_computed_at":"2026-06-19T16:11:55.350675Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-19T16:11:55.350675Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"grwFdHQ7IAmFkY4T5924D2CvRFlOTJ1ti/X2esQntcxki9NmqNtM+589zXXLkQVNyRIb1HOLpP97gMWO1XxJCg==","signature_status":"signed_v1","signed_at":"2026-06-19T16:11:55.351022Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.19048","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6a7fa2aa446fa3081ef9509765b974e13974131b58eec4a44cb0994e64139e9c","sha256:b5863f19bbe88cdcd7552b15f6feafd5fe4d19e82b9ae4511a2e9e93cf573686"],"state_sha256":"32e7d3022ea96451b2d0ccc11d67325553e27c3c0b6c4b5562073962b118d00c"}
