The disk is geometrically thin and general relativistic with a non-rotating central source. A Lagrangian formulation is adopted. The author examined the same problem a few years ago, but here we derive a general stability criterion in a more perspective way. Another distinct point from the previous work is that in addition to the case where the deformation is a warp, the case where the deformation is a one-armed pattern symmetric with respect to the eq","authors_text":"Shoji Kato","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2007-09-16T07:00:37Z","title":"Resonant Excitation of Disk Oscillations in Deformed Disks II: A Model of High Frequency QPOs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0709.2467","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":"sha256:7050a0a57d9e1e9a2c920165c2f5da19dfd548e2e944b270a0db5caf8e823661","target":"record","created_at":"2026-05-18T02:16:11Z","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":"1d95c2f3e61d23b6e6543c9db89dff63c59eaa7f3ab73ebe8190fba90c12ad61","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2007-09-16T07:00:37Z","title_canon_sha256":"998ee5ea3c9c036b029db595fe94a8d723b838fc78a5aa6605e570f82c186ffa"},"schema_version":"1.0","source":{"id":"0709.2467","kind":"arxiv","version":1}},"canonical_sha256":"e97c37bd8d3d402a9fd27ef66382c65c197af6937338fc9b6b5c49d4db0c704a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e97c37bd8d3d402a9fd27ef66382c65c197af6937338fc9b6b5c49d4db0c704a","first_computed_at":"2026-05-18T02:16:11.218802Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:16:11.218802Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Zx74eQwV7rA/vExbq4dL/H8yeI+MkzG+6ScG0Efso/5kZOPgJMu/7/wr+M/uDxIEgfWaRvstWbhzBegnC96MCA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:16:11.219554Z","signed_message":"canonical_sha256_bytes"},"source_id":"0709.2467","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7050a0a57d9e1e9a2c920165c2f5da19dfd548e2e944b270a0db5caf8e823661","sha256:6890539c9509dca06483335b698021333419e10f5f227d0313855fb2ea2ed9cd"],"state_sha256":"4ab949d4cfa357f99333a54493eec49ecb0c06e69851b829367d442d098fdae8"}
