At core bounce, progenitors with rapid core rotation rates exhibit a characteristic GW signal which can be used to constrain the properties of the core of the progenitor star. We investigate the dynamics of rapidly rotating core collapse, focusing on hydrodynamic waves generated by the core bounce and the GW spectrum they produce. The centrifugal distortion of the rapidly rotating proto-neutron star (PNS) leads to the generation of axisymmetric quadrupolar oscillations within the ","authors_text":"Christian Ott, Ernazar Abdikamalov, Hannah Klion, Jim Fuller","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2015-01-27T22:51:31Z","title":"Supernova Seismology: Gravitational Wave Signatures of Rapidly Rotating Core Collapse"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1501.06951","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":"sha256:4e6607a309713226e94683dc9759bdc614e33b427fdf0d1ce02709e5ff46c7d3","target":"record","created_at":"2026-05-18T02:17:33Z","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":"d2d7babf7dc8e4352c30eece7c1d7fe0dfce0ad89b7a9c8c0eea321899a0d652","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2015-01-27T22:51:31Z","title_canon_sha256":"9bfa915abecbffd4b536b72dd3c0e05ee3077647bf7d5a1ec2645fdfa2177dd2"},"schema_version":"1.0","source":{"id":"1501.06951","kind":"arxiv","version":2}},"canonical_sha256":"73f6ebf12d05ab5012930c1cde2d0f54c7c0b71b9a42907572a8deec9ad59818","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"73f6ebf12d05ab5012930c1cde2d0f54c7c0b71b9a42907572a8deec9ad59818","first_computed_at":"2026-05-18T02:17:33.216933Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:17:33.216933Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"mB3KRpmEci65SSK5s01BwNiEhZwAVKGEtmMHWC2xjVisv40cdmXllSsx+33nG8zzkjeMhJOd9G2KPxv4xMv0DA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:17:33.217632Z","signed_message":"canonical_sha256_bytes"},"source_id":"1501.06951","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4e6607a309713226e94683dc9759bdc614e33b427fdf0d1ce02709e5ff46c7d3","sha256:8436a5c5dcfe1b8b55e91539f6c78fc3e18289858e8cb4e27267ba635cdad647"],"state_sha256":"470f81432d44917ac935d06d7c4ea3afe907dc0baadd20b2d09eabd7ef4fa0c5"}
