Exoplanet atmospheres can be chemically extremely rich. Exoplanet clouds are therefor made of a mix of materials that changes throughout the atmosphere. They affect the atmospheres through element depletion and through absorption and scattering, hence, they have a profound impact on the atmosphere's energy budget. While astronomical observations point us to the presence of extrasolar clouds and make first suggestions on particle sizes and material compositions, we requ","authors_text":"Christiane Helling (Centre for Exoplanet Science, University of St Andrews)","cross_cats":["astro-ph.SR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2018-12-10T13:45:44Z","title":"Exoplanet Clouds"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.03793","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":"sha256:363d3632226e020e5852bd8b15f2ce48a6177ad32d0ffd9b46ad87a84ae82773","target":"record","created_at":"2026-05-17T23:43:37Z","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":"72381e72dc5dd078fdb579ccb63d462763cf032d881531199ce93bb8c0cd5ab8","cross_cats_sorted":["astro-ph.SR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2018-12-10T13:45:44Z","title_canon_sha256":"517ceb7147a53a0e35d334cc8b9143571316bc1f797d88a186863890b027121a"},"schema_version":"1.0","source":{"id":"1812.03793","kind":"arxiv","version":1}},"canonical_sha256":"a26bc40796f515c20afd941992c8813a5e2d166aa1800762099cce64825f3841","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a26bc40796f515c20afd941992c8813a5e2d166aa1800762099cce64825f3841","first_computed_at":"2026-05-17T23:43:37.637230Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:43:37.637230Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1Blt/4kvXIZiGS4v9G1wiaOs4AYEevYAOaLJmmJ0fxIoTf0qb+LarYk2YTFFnUli7IWk+iHauq9/k9jpJ8TIAA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:43:37.637697Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.03793","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:363d3632226e020e5852bd8b15f2ce48a6177ad32d0ffd9b46ad87a84ae82773","sha256:0b3b53bc973066c2fe4fd3e98cafc8dd3d6d1903a8e6abc90da31eb9cde3248d"],"state_sha256":"803ab1de99df4c4a57f74160b0de5ef5da5207ac9bb8281a1f932a2cefea1cf8"}
