The physical origin of this variability, called S Doradus cycle after its prototype, has remained elusive. Here, we study the feedback of stellar wind mass-loss on the envelope structure in stars near the Eddington limit. We perform a time-dependent hydrodynamic stellar evolutionary calculation, applying a stellar wind mass-loss prescription with a temperature-dependence inspired by the predicted sy","authors_text":"Andreas Sander, Goetz Graefener, Jonathan Mackey, Jorick Vink, Luca Grassitelli, Nathan Grin, Norbert Langer","cross_cats":["astro-ph.HE"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2020-11-30T19:00:05Z","title":"Wind-envelope interaction as the origin of the slow cyclic brightness variations of luminous blue variables"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2012.00023","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:e6e360cee62d0cef4796688b778f1980fa1f51fb7503e916b4dece3b27abfe1a","target":"record","created_at":"2026-07-05T02:23:50Z","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":"29d70652b38eb071cf77cc6e752e0b7456388e4e2e5d2d3a9edbda7ac1f430d5","cross_cats_sorted":["astro-ph.HE"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2020-11-30T19:00:05Z","title_canon_sha256":"7ae64cbceeb5a1724e6b3b6f260a8609f2182545bbffbb5953c26e197108cfc5"},"schema_version":"1.0","source":{"id":"2012.00023","kind":"arxiv","version":2}},"canonical_sha256":"3c2e82a4684e3920e829ac76abc6ea148525504119e48d2d99d4fca945f179bf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3c2e82a4684e3920e829ac76abc6ea148525504119e48d2d99d4fca945f179bf","first_computed_at":"2026-07-05T02:23:50.053328Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:23:50.053328Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hnLd4eMmYm6yDMTJ2fYwQ05AUt5kSS4zYokzP+HLWLQTvtCzFygBbIP8HDcC1GgnT2vdafSzL67e1z3ywb9kCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T02:23:50.053746Z","signed_message":"canonical_sha256_bytes"},"source_id":"2012.00023","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e6e360cee62d0cef4796688b778f1980fa1f51fb7503e916b4dece3b27abfe1a","sha256:57bf3188b825190690d2b16c906fc34e1e0bd5c9817f98c2ea9c1446c9a12897"],"state_sha256":"6bd75394939a0e0167b818ab6c0befedeed62484ae55f592ab74f5575a595207"}
