We assume that the flows are non-rotating and exposed to quasar radiation. We take into account X-ray heating and the radiation force due to electron scattering and spectral lines. To compute the radiation field, we consider a standard accretion disk as a source of UV photons and a spherical central object as a source of X-rays. The gas temperature and ionization state in the flow are calculated self-consistently from the photoionization and ","authors_text":"Daniel Proga","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2007-02-21T20:54:27Z","title":"Dynamics of Accretion Flows Irradiated by a Quasar"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0702582","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":"sha256:303b8e370d5ba6b214f5bb34e35b830ca7db747d0b2f8168ad3b3f27ddabc89c","target":"record","created_at":"2026-05-18T04:29:06Z","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":"767d5d9e5abf0c17585c5f6d94482db0a3645b6bf8aea8b80af9b93c140ac785","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2007-02-21T20:54:27Z","title_canon_sha256":"4e7d34756b4efba1856d49e270025091e5304091b4f821ee14859543fefe12cb"},"schema_version":"1.0","source":{"id":"astro-ph/0702582","kind":"arxiv","version":1}},"canonical_sha256":"4dbafe0a5c2addaa7ef82a513cafec896b817db4e196fa43f18ce9a3a1628bce","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4dbafe0a5c2addaa7ef82a513cafec896b817db4e196fa43f18ce9a3a1628bce","first_computed_at":"2026-05-18T04:29:06.302296Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:29:06.302296Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"V7SMauK/EaY4e72w3q/WZiZKu4+WagyZ3iA0fKuVPArvqiZtu7wLDNEm1AxGSQ5uXvWKEXNl47BC9YMxLaH2DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:29:06.302814Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0702582","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:303b8e370d5ba6b214f5bb34e35b830ca7db747d0b2f8168ad3b3f27ddabc89c","sha256:1c34739f8762e1456af4ac749ce273a1e0b0026f7efa1578452ece7bce24d0c0"],"state_sha256":"cb524886cc7865517c391c7fccc617b14d0b43142d85bc6ad8995be7765d1191"}
