In this paper we investigate whether that solution can emerge as a result of gravitational collapse of matter. With this goal, we study the simplest kind of spherically-symmetric matter: an infinitely-thin shell of dust. Our system can be understood as a model of a star accreting a thin layer of matter. We solve the dynamics of the shell ex","authors_text":"Andrea Napoletano, Flavio Mercati, Henrique Gomes, Tim Koslowski","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2015-09-02T19:46:40Z","title":"Gravitational collapse of thin shells of dust in asymptotically flat Shape Dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.00833","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:b5413af8ea18744bde47ff4faa79962cf36be69a88b78aea4d23e7494478733a","target":"record","created_at":"2026-05-18T00:50:22Z","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":"d43c2e68295c83acf6f9671ac4159ff7413b2c061a0391fb140632a0b1c95653","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2015-09-02T19:46:40Z","title_canon_sha256":"99c66be5170c803c339e0985fea0921b95f9b5282336d784e6950b958913d4d9"},"schema_version":"1.0","source":{"id":"1509.00833","kind":"arxiv","version":2}},"canonical_sha256":"195c98a564a703030eb8faff8cbfc212c87ebdf4c11fea69d39f3f11ac43ba0b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"195c98a564a703030eb8faff8cbfc212c87ebdf4c11fea69d39f3f11ac43ba0b","first_computed_at":"2026-05-18T00:50:22.970416Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:50:22.970416Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EIZVtrTLj/ytsYx6IzSBpFCfi808T0+HrNZyXVF280ObDGriLCE7tLQwSxa2m8QnFhZT7WEyZpDTBTg0MJxWBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:50:22.971241Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.00833","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b5413af8ea18744bde47ff4faa79962cf36be69a88b78aea4d23e7494478733a","sha256:012eaab19886b58e836bab85522bf90f353d6de46ed0720b1ac424f2eeaada46"],"state_sha256":"d3446770db4371f643b2281843ff0bd38c7f8e4a72d5e86fea05b179c71012b9"}
