Under such a precision, astrometry will play important roles in detecting and characterizing exoplanets. Specially, we can identify planet pairs in mean motion resonances(MMRs) via astrometry, which constrains the formation and evolution of planetary systems. In accordance with observations, we consider two Jupiters or two super-Earths systems in 1:2, 2:3 and 3:4 MMRs. Our simulations show the false alarm probabilities(FAPs) of a third planet are extremely small while the real two planets can be good fitted with s","authors_text":"Dong-Hong Wu, Hui-Gen Liu, Hui-Zhang, Ji-Lin Zhou, Zhou-Yi Yu","cross_cats":["astro-ph.IM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2016-12-11T07:47:44Z","title":"Detecting planet pairs in mean motion resonances via astrometry method"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1612.03381","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":"sha256:30cc07ebe8daad5d4337625028e41aec2e7ab046e8510abe7810930aa517f5ee","target":"record","created_at":"2026-05-18T00:54:10Z","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":"210a3cf294babd1f7d0e6b91e974345a79e2db1979d6aa500e8b52b2d698e549","cross_cats_sorted":["astro-ph.IM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2016-12-11T07:47:44Z","title_canon_sha256":"159ee967d1d524fc7a5747957fa371ed8f388c632ede25cd93e02184724700df"},"schema_version":"1.0","source":{"id":"1612.03381","kind":"arxiv","version":1}},"canonical_sha256":"f698afe16b3c05542ac4bc25cbb89c5cb93830317a977171d6d0caefb598f8b3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f698afe16b3c05542ac4bc25cbb89c5cb93830317a977171d6d0caefb598f8b3","first_computed_at":"2026-05-18T00:54:10.328508Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:54:10.328508Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7bAqYbDjutiGC64+w290UVXFs5R5n+Kunon8vhpILXQyUx2x53Jm2EmmFJ80ToULnM8b3P89orH9WPz41eLZBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:54:10.328968Z","signed_message":"canonical_sha256_bytes"},"source_id":"1612.03381","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:30cc07ebe8daad5d4337625028e41aec2e7ab046e8510abe7810930aa517f5ee","sha256:23f999aa3d56311eea049a52fe01ac7e81486c74cc8ffe7c1f569e8771166e5c"],"state_sha256":"9abcae9d11a928b790216519661b6e6a5eed7fe3724a04d0fdca316235b1eca1"}
