The origin of the valley is normally attributed to mass-loss process such as photoevaporation or core-powered mass loss. Recent work, however, has suggested that the radius valley may instead arise as a consequence of gas accretion by low-mass planets. In this work we therefore aim to investigate the formation of a primordial radius valley from the formation of planet cores through pebble accretion up unt","authors_text":"Anders Johansen, Caroline Dorn, Jesper Nielsen, Komal Bali","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.EP","submitted_at":"2025-02-14T14:25:02Z","title":"A primordial radius valley as a consequence of planet formation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.10186","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":"sha256:93928305faa6863ce2ba86dd1ac1afa4e56cc11954d1bb750c3135041b8637b1","target":"record","created_at":"2026-07-05T10:33:44Z","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":"19a29df759e8f94076a08e2b416357e30a4cf48b7080e36cae6accee026f4a11","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.EP","submitted_at":"2025-02-14T14:25:02Z","title_canon_sha256":"98d052dd753d03808dc6757874b042c40ff11604b40106885526738cb28153ed"},"schema_version":"1.0","source":{"id":"2502.10186","kind":"arxiv","version":1}},"canonical_sha256":"37e2709e2d9026af9c0e318fc00ca347540be69d671a9dc985daf80036cc1cbf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"37e2709e2d9026af9c0e318fc00ca347540be69d671a9dc985daf80036cc1cbf","first_computed_at":"2026-07-05T10:33:44.497185Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:33:44.497185Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"c3pgpxn8AxOXHyOcuKNYc3tdxMpBQxwlZxvPGgejzSPAwEED8VMlii+4uZsckAMMu0GBDg6pXgWyeLUoAnRQBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:33:44.497664Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.10186","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:93928305faa6863ce2ba86dd1ac1afa4e56cc11954d1bb750c3135041b8637b1","sha256:86965fea7855c527740594f5b8849da109b6eef3cb67efb318e395ff13a670b2"],"state_sha256":"b1570e53f6e3b0919a501560784c279004e0a09a657e1ee1827c158752f39ed8"}
