Among other evidence for a mechanism of evaporation at work on the ground, dry lakebeds have been discovered. Recent Cassini infrared observations of these empty lakes have revealed a surface composition poor in water ice compared to that of the surrounding terrains --- suggesting the existence of organic evaporites deposits. The chemical composition of these possible evaporites is unknown. In this paper, we study evaporite composition using a model that treats both organic solids dissolution and solvent ev","authors_text":"Abel Ferreira, Daniel Cordier, Jason Barnes","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2013-08-22T13:24:35Z","title":"On the chemical composition of Titan's dry lakebed evaporites"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1308.4856","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:ce89d0048179f207d45b7009497f9bfcf38a078947bc0ab316dfc29354562bbd","target":"record","created_at":"2026-05-18T01:48:04Z","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":"0ccaed70b3ef7b1f3ebbb5595542dc0d01c48494a9109cef83b5cd4a5f27fae3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2013-08-22T13:24:35Z","title_canon_sha256":"3b35f28ca04c1bab6dcea235e5dab68d777491638f2927fb4440b0fcd70bf166"},"schema_version":"1.0","source":{"id":"1308.4856","kind":"arxiv","version":1}},"canonical_sha256":"04098f2ddfff98624de53fdf851d9789ed802f4be49135a950789f3344f4e481","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"04098f2ddfff98624de53fdf851d9789ed802f4be49135a950789f3344f4e481","first_computed_at":"2026-05-18T01:48:04.687606Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:48:04.687606Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1HZM31qI+vUoVeOsRsyQ7ehw+a3SpZLod2AbUtb3d22N5sZF77wKU/Wibu5emQKCTsq3Oy7Zh+1tHiuqohACBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:48:04.688244Z","signed_message":"canonical_sha256_bytes"},"source_id":"1308.4856","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ce89d0048179f207d45b7009497f9bfcf38a078947bc0ab316dfc29354562bbd","sha256:24a92a9109815edca386f4ef0e2fcc1206e23b66797186bb490a29296f305986"],"state_sha256":"a5aa436a27558e80af301e3e1ac6f19b50648363d2d1a43b1f5da667eed6e6a8"}
