SN2023ixf can be explained as an explosion of a massive star with an energy of 0.7e51 erg, however with a greatly reduced envelope mass, probably because of binary interaction. In our radiative-transfer simulations, the SN ejecta of 6 Msun interact with circumstellar material (CSM) of ~0.6 Msun extending to 1.e15 cm, which results in a light curve (LC) peak matching that of SN2023ixf. The origin of this required CSM might be gravity wav","authors_text":"Alexandra Kozyreva, Alexey Mironov, Andrea Caputo, Hans-Thomas Janka, Petr Baklanov","cross_cats":["astro-ph.SR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.HE","submitted_at":"2024-10-25T19:20:56Z","title":"SN 2023ixf -- an average-energy explosion with circumstellar medium and a precursor"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2410.19939","kind":"arxiv","version":2},"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:a650d3f6503aedc9ec1fc6ca40a62937839bc04669648b706155c2ddf01b41d5","target":"record","created_at":"2026-07-05T10:19:30Z","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":"be4f002c0eb9523273b2760852405d94614d6fe8ce1371ed086f5fbb0319afde","cross_cats_sorted":["astro-ph.SR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.HE","submitted_at":"2024-10-25T19:20:56Z","title_canon_sha256":"8d3d0505987d0c248a61fe4717afee66461be10ac44dfe46cea8b30a8205ab20"},"schema_version":"1.0","source":{"id":"2410.19939","kind":"arxiv","version":2}},"canonical_sha256":"eeb61782a26f00cad24dfac866bd435f522f5f22bfce382b13468b3f20aefc6a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eeb61782a26f00cad24dfac866bd435f522f5f22bfce382b13468b3f20aefc6a","first_computed_at":"2026-07-05T10:19:30.274758Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:19:30.274758Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"G/1so+QIVjjfXdvCogLzTh4+wFLBdugXIHxjcV1IsVNZsTCGPs/i7rq/n7KcVo+I91H8E9HjqytSzHzcNR8aBA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:19:30.275213Z","signed_message":"canonical_sha256_bytes"},"source_id":"2410.19939","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a650d3f6503aedc9ec1fc6ca40a62937839bc04669648b706155c2ddf01b41d5","sha256:5fce3071e401def6448adb1918d8ad534c8ddd9a152ea766c3f15223688347ed"],"state_sha256":"be4f55981d50d3de00028e80b217e435e0571312ff517c24f9942739f66ba45d"}
