Several previous studies have considered the emission resulting from the accretion of bound material; we consider the possibility that the unbound debris may also radiate once it has expanded and become transparent. We show that the gradual energy input from hydrogen recombination compensates for adiabatic loses over significant expansion factors. The opacity also drops dramatically with recombination, and the interna","authors_text":"Daniel Kasen, Enrico Ramirez-Ruiz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-11-28T17:05:19Z","title":"Optical Transients from the Unbound Debris of Tidal Disruption"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0911.5358","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:f45616b418f67e58b41c07372ad7d0d4a779a001e31c5226fcc7d748d405c167","target":"record","created_at":"2026-05-18T02:34:03Z","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":"d81afcce1b2797d4982f543807de9fa26be38edc57089206dd7bc072f2adf407","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-11-28T17:05:19Z","title_canon_sha256":"b4bfaf1bb9c22d71b21f0747f813a3688269f4265fa9b78640b961dab18bde01"},"schema_version":"1.0","source":{"id":"0911.5358","kind":"arxiv","version":1}},"canonical_sha256":"af0c8295dda3a2e94a4d39c590ac29850f1ca7d13fa718f4a8c869c6adc6b50f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"af0c8295dda3a2e94a4d39c590ac29850f1ca7d13fa718f4a8c869c6adc6b50f","first_computed_at":"2026-05-18T02:34:03.198131Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:34:03.198131Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lFTOvxcqj3XX3y67i74uye+O0GFRnIDGuAvxDbjHJruTlDE0BMReXW0ih5E2as0fosxiPcFFRmMwI4G6+BoRDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:34:03.198730Z","signed_message":"canonical_sha256_bytes"},"source_id":"0911.5358","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f45616b418f67e58b41c07372ad7d0d4a779a001e31c5226fcc7d748d405c167","sha256:7ed7e0459b6b242c2bed1c85db35948c7d7091369d5c3d017d3152c86681f552"],"state_sha256":"406aae9d94a05bac4e01f5388db9fca52996547279832c8a0caa281af13a893b"}
