The temperature is taken to be 10K or 100K, the mean number density is either 100cm^3 or 300cm^3. Besides, the turbulence is varied between Mach 1.5 and Mach 12.5 and the main driving scale between 1pc and 8pc. We vary the ionizing flux by an order of magnitude. In our simulations the ionizing radiation enhances the initial turbulent density distribution and thus leads to the formation o","authors_text":"Andreas Burkert, Matthias Gritschneder, Stefanie Walch, Thorsten Naab","cross_cats":["astro-ph.GA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2010-08-31T20:00:16Z","title":"Detailed Numerical Simulations on the Formation of Pillars around HII-regions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1009.0011","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":"sha256:5c49f6fdea68de943eaad856514f6b2ef397b42673f2362ca7d12a647891162b","target":"record","created_at":"2026-05-18T02:05:38Z","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":"832d4a7e93176f61e4db6b102a3935923e048b2750b45d758c9448e5a42d55a0","cross_cats_sorted":["astro-ph.GA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2010-08-31T20:00:16Z","title_canon_sha256":"e0a4fa7dd5119874049b0c1baeca5d85eba8a18e97b4d5a3c0e3f2185b991ae3"},"schema_version":"1.0","source":{"id":"1009.0011","kind":"arxiv","version":1}},"canonical_sha256":"9f2ebc1fea0a994826f78bb1d04bd3150737fdb147d29eaba14e08eec6ba55de","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9f2ebc1fea0a994826f78bb1d04bd3150737fdb147d29eaba14e08eec6ba55de","first_computed_at":"2026-05-18T02:05:38.887634Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:05:38.887634Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"W13epKPT0lI0SgGn4dXmJFMOZ+ib4lPivYNE5L4Oz2ZBnp1PKJDcRf7UKdYvvlzJpZNL7eCn6grfMJB1rsrfDw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:05:38.888356Z","signed_message":"canonical_sha256_bytes"},"source_id":"1009.0011","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5c49f6fdea68de943eaad856514f6b2ef397b42673f2362ca7d12a647891162b","sha256:88c901bb25fdc3f9c19fe2b1f7e59b03acc966c51749df5d7aa68fc23bf83813"],"state_sha256":"8be1e5b2f616d5eae6e6368d59793036cdacd62ae1c74e47a5c8db8d51aab702"}
