WIMP self-interactions mediated by Yukawa- type interactions can lower significantly the number of WIMPs necessary for gravitational collapse of the WIMP population accumulated in a neutron star. Even nearby neutron stars located at regions of low dark matter density can accrete sufficient number of WIMPs that can potentially collapse, form a mini black hole, and destroy the host star. Based on this, we derive constraints on the WIMP self-interactions","authors_text":"Chris Kouvaris","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2011-11-18T13:54:35Z","title":"Limits on Self-Interacting Dark Matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1111.4364","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:bb39b2894414586f73df19a7f25e7dbc304356fad4905532770c1f6136cb1b1f","target":"record","created_at":"2026-05-18T01:59:29Z","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":"bd3e7837b478b223d66810bde88fa4060881f59c9306444596a7ce1ffdb611ab","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2011-11-18T13:54:35Z","title_canon_sha256":"12ec601184b60db31bed529e148d2d11e38827777a998a4a2c41954d3d350473"},"schema_version":"1.0","source":{"id":"1111.4364","kind":"arxiv","version":1}},"canonical_sha256":"4365326bb4b772c165b259bf503e4a518427f2dea816cc151f280732af1fc432","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4365326bb4b772c165b259bf503e4a518427f2dea816cc151f280732af1fc432","first_computed_at":"2026-05-18T01:59:29.296647Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:59:29.296647Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hsfcFIqXYMklH8DkhO0KR1W7bMw22sU8UI2/zvepqZjq1gFwzPx9o/sVZGsMRnMACUQ7HK/Q7U6J003e3VtiCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:59:29.297244Z","signed_message":"canonical_sha256_bytes"},"source_id":"1111.4364","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bb39b2894414586f73df19a7f25e7dbc304356fad4905532770c1f6136cb1b1f","sha256:4a21aca24824d918005e6af594d84432492b20725b7e4e4a8050ac6992d6e3f0"],"state_sha256":"7a442c7ee1a51aa80969df3881ec2d5dfbe40784b7b468c424e65c469d474c7d"}
