At the same time, recent observations find significant $r$-process enrichment even in extremely small ultra-faint dwarf (UFD) galaxies. This raises the question of retainment of those elements within their hosts. We estimate the retainment fraction and find that it is large $\\sim 0.9$, unless the $r$-process event is very energetic ($\\gtrsim 10^{52}$erg) and / or the host has lost a large fraction of its gas prior to the event. We estimate the $r$-process mass per event and rate as implied by abundances i","authors_text":"Irina Dvorkin, Joe Silk, Paz Beniamini","cross_cats":["astro-ph.GA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-11-07T19:00:53Z","title":"Retainment of r-process material in dwarf galaxies"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.02683","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":"sha256:531da1bbd3f357e9780b77e1d557bf410725a7bbccf457d94bce865d23b6394b","target":"record","created_at":"2026-05-18T00:11:23Z","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":"d79d54f0247a8aa82ac9c231ec8e80b580a5651e7183207aece2ed339b4eb68e","cross_cats_sorted":["astro-ph.GA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-11-07T19:00:53Z","title_canon_sha256":"5d6c6218176ba9a2155af9e6db1b4dda3e047d87cdf6fe21333bf858bc1637d8"},"schema_version":"1.0","source":{"id":"1711.02683","kind":"arxiv","version":2}},"canonical_sha256":"52aa54eb6b9557cfcd39597e59e2933c3498982c5d9aec5f3e76125b77728d37","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"52aa54eb6b9557cfcd39597e59e2933c3498982c5d9aec5f3e76125b77728d37","first_computed_at":"2026-05-18T00:11:23.678482Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:11:23.678482Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+iSI9xapm847Npb3YDGRMJFrBH0gWcPWwLd2qLMwspuviy8aTwf0jiLu+bQg1JGrtM0mt9iDLoditpPLgKuJCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:11:23.678971Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.02683","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:531da1bbd3f357e9780b77e1d557bf410725a7bbccf457d94bce865d23b6394b","sha256:b60c55d6edb0a761d82dd2ec7003a0f9ea8a18cf580d4c4745b8bf7b2b6f1dbb"],"state_sha256":"b9be2b7adf8b1a3be865241286808370dbf1cb90169287291749fe47bc2e0e0e"}
