We conduct a systematic investigation of such degeneracies using a combination of detailed atmospheric retrievals and a range of model assumptions, focusing on H$_2$-rich atmospheres. As a case study, we consider the well-studied hot Jupiter HD 209458 b. We perform extensive retrievals with models ranging from simple isothermal and isobaric atmospheres to those with full pressure-temperature profiles, inhom","authors_text":"Luis Welbanks, Nikku Madhusudhan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2019-04-10T18:00:00Z","title":"On degeneracies in retrievals of exoplanetary transmission spectra"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.05356","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":"sha256:1cd9ff45aabe747d3ece87b31f48544d2f42a60f681fed62e21d8380c75a4e86","target":"record","created_at":"2026-05-17T23:46:52Z","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":"5ee8cdef43c68d70f988e64a28a40c81bb977855cb9ef377b0353fedca8dc2ab","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2019-04-10T18:00:00Z","title_canon_sha256":"2ff4826c1cae6fac6c285201672f8e9bbf6f5ca0105c421c9758b6a8b9a4a18e"},"schema_version":"1.0","source":{"id":"1904.05356","kind":"arxiv","version":1}},"canonical_sha256":"5716a6aa9d2c8be6a7bae7696eb2a000c9996d5cab32c6ac5d81dc136b4481ff","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5716a6aa9d2c8be6a7bae7696eb2a000c9996d5cab32c6ac5d81dc136b4481ff","first_computed_at":"2026-05-17T23:46:52.449698Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:46:52.449698Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+T9L4laGw4QfJbfoe5PDP5UVylU7ugj650QIRdYaUES3h8mcfAfyjG8m2mXU5VYyjqGhVLuz9Y9aLphx/WW2CA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:46:52.450185Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.05356","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1cd9ff45aabe747d3ece87b31f48544d2f42a60f681fed62e21d8380c75a4e86","sha256:fcf9ced8af8590ae717e302c4a2bcc7ef81dc5ca23ad9f1410046b109f79104b"],"state_sha256":"2115f1098a089d12c6c4e7a0d2eacbac0fdcb54ea163a9eb21fd99782de86f90"}
