Because land planets can emit a large amount of radiation from the dry tropics, they have a higher runaway threshold than aqua planets do. Here we systematically investigated the runaway threshold for various surface water distributions using a three-dimensional dynamic atmosphere model. The runaway threshold for the meridionally uniform surface water distribution increases from the typical value for the aqua-p","authors_text":"Ayako Abe-Ouchi, Hidenori Genda, Ryouta O'ishi, Takanori Kodama, Yutaka Abe","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2019-08-16T09:33:41Z","title":"Inner Edge of Habitable Zones for Earth-sized Planets with Various Surface Water Distributions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.05909","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":"sha256:95bff70530005b11500ed747065b566da06d70f748310340f03134ac80e9a824","target":"record","created_at":"2026-07-05T00:30:21Z","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":"4705f33009348b918d63b407c9257a79cc0b5617252cb77071bd245faa31fe2c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2019-08-16T09:33:41Z","title_canon_sha256":"02b8c43f844dcb1207b67a083b819893e6468212eb848fbb7f4b62d58ae36cd6"},"schema_version":"1.0","source":{"id":"1908.05909","kind":"arxiv","version":1}},"canonical_sha256":"0601a5078afb28907b7db27e24582f219a8f942ff87eb3840940843dcdbb7783","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0601a5078afb28907b7db27e24582f219a8f942ff87eb3840940843dcdbb7783","first_computed_at":"2026-07-05T00:30:21.191904Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:30:21.191904Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"SGgmbF9kIBf3wPoJrJERKprUFsz5RCGSx5CCv/zeTc2kCD9qIwIzMvrYNkK6m5gyv05i3Bwimr7fmoK2KBrEBw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:30:21.192336Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.05909","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:95bff70530005b11500ed747065b566da06d70f748310340f03134ac80e9a824","sha256:1873bc7079ff488fa71ef08e5f84b24e2039ef31b7c609a46b882d8c0819d7a5"],"state_sha256":"77000977fb265b029b9c07379a85758c209e270dcfc9db5105feb896cde1db1e"}
