At a redshift of z = 0.01368, TDE 2025aarm is the second closest TDE ever discovered, offering an unprecedented opportunity to study such phenomena in great details. We observed TDE 2025aarm in optical with the Liverpool Telescope for a total of three epochs, and complemented our dataset with ancillary spectroscopic and photometric data. The early optical spectra are characterized by a blue-continuum and helium, hydrogen and possibly Bowen lines typical of H"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Our analysis suggests that the early emission from TDE 2025aarm is powered by circularization shocks, and that the delayed accretion scenario best describes the observed features.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The optical light curves are well described by the fallback of a 0.16 solar mass star onto a 2x10^7 solar mass black hole, which assumes the standard TDE fallback model applies without significant systematic uncertainties or alternative emission mechanisms.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Early multi-wavelength data from TDE 2025aarm indicate emission powered by circularization shocks with delayed accretion onto a ~2x10^7 solar mass black hole.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Early multi-wavelength data on TDE 2025aarm indicate its initial emission arises from circularization shocks under a delayed accretion picture.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"2c07d40b55d814d4b900452f0ac1860f79a21683c23e7052f1fd8936c4f18e53"},"source":{"id":"2603.20123","kind":"arxiv","version":3},"verdict":{"id":"51c86183-eb5d-4c3e-ac47-b346b81b0999","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-15T07:01:19.781354Z","strongest_claim":"Our analysis suggests that the early emission from TDE 2025aarm is powered by circularization shocks, and that the delayed accretion scenario best describes the observed features.","one_line_summary":"Early multi-wavelength data from TDE 2025aarm indicate emission powered by circularization shocks with delayed accretion onto a ~2x10^7 solar mass black hole.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The optical light curves are well described by the fallback of a 0.16 solar mass star onto a 2x10^7 solar mass black hole, which assumes the standard TDE fallback model applies without significant systematic uncertainties or alternative emission mechanisms.","pith_extraction_headline":"Early multi-wavelength data on TDE 2025aarm indicate its initial emission arises from circularization shocks under a delayed accretion picture."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2603.20123/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":2,"snapshot_sha256":"5cd89066972082c1b82626559b2a6e35a5ea7fd051d2249a9359754b785191d2"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
