Here I show that these patterns can be largely explained by detection biases. The \\emph{Kepler} planet detections are set by the transit signal-to-noise ratio (S/N). For different stellar properties and orbital period values, the same S/N corresponds to different planetary sizes. This variation in the detection threshold naturally leads to apparent correlations in planet sizes and the ","authors_text":"Wei Zhu (CITA)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2019-07-03T18:00:01Z","title":"On the patterns observed in Kepler multi-planet systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.02074","kind":"arxiv","version":3},"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:e2b1733ac3108355d7a1471d291ff6b6fa939806ab86970d5df30724edf6f5fc","target":"record","created_at":"2026-07-05T00:55:02Z","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":"b3c839d77f3873dbdcda78447ebebe0ae00a712e8173e981230a26ec3d6c2d3b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2019-07-03T18:00:01Z","title_canon_sha256":"082e93686ece75423531519e17fb17b3f1e7175b84fe364f9a51a4f9b70689b0"},"schema_version":"1.0","source":{"id":"1907.02074","kind":"arxiv","version":3}},"canonical_sha256":"624064410362de4c7f143dd3d95e161962e9ab48189a18794836ac61c7d8fb0e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"624064410362de4c7f143dd3d95e161962e9ab48189a18794836ac61c7d8fb0e","first_computed_at":"2026-07-05T00:55:02.565965Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:55:02.565965Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NDrKQECaAQ9U3cJL7SsBPbqLqGkLV56QOk/NhHjILZ4jslmLsl7uHbNva8e0ySJfCnGdRmcqps3Fo+qJ1Tv0Dg==","signature_status":"signed_v1","signed_at":"2026-07-05T00:55:02.566364Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.02074","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e2b1733ac3108355d7a1471d291ff6b6fa939806ab86970d5df30724edf6f5fc","sha256:8b38efcce2bea78b007003f491771f4c46d31bd214832e06ba8264bf55863bc5"],"state_sha256":"ac89eb16c173fd04af1bfc6a108a01e07bec6851d8689cb8bb34de039f70d718"}
