We firstly extend the analysis present in the literature relaxing the ideal-gas properties of the string-hole gas, taking into account a (bulk-)viscosity term. Then we consider the case of a theory described by a complete O(d,d)-invariant action up to all orders in $\\alpha^{\\prime}$-corrections (the Hohm-Zwiebach action), studying the stability of the string-hole gas solution with or without the introduction of the viscosity term. Furthermore, the bulk viscosity is also c","authors_text":"Denis Bitnaya, Giovanni Marozzi, Pietro Conzinu","cross_cats":["astro-ph.CO","gr-qc"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-th","submitted_at":"2023-08-31T14:33:11Z","title":"On the stability of string-hole gas"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.16764","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":"sha256:3311df025f09c0fbd1c0982511f37b8f0f9e9263b4ff5d9f8942446e08751b72","target":"record","created_at":"2026-07-05T07:20:40Z","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":"f2fbc9d70a7fdec43eb46c12b08f319cfacbee49159b974990cc13f82db154dd","cross_cats_sorted":["astro-ph.CO","gr-qc"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-th","submitted_at":"2023-08-31T14:33:11Z","title_canon_sha256":"647efc2045c8adf417eee5a9cdd83889c09239ff6ed12d8fda66661a57b8fa31"},"schema_version":"1.0","source":{"id":"2308.16764","kind":"arxiv","version":2}},"canonical_sha256":"09feb49e7bdb87206f840f93e2d2f9a826aa9260d51ad157cad9188885bfba1d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"09feb49e7bdb87206f840f93e2d2f9a826aa9260d51ad157cad9188885bfba1d","first_computed_at":"2026-07-05T07:20:40.231229Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:20:40.231229Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JNYH2JXLCjXlsRd/UUHeHipIRbV8VsPbUqqZs+Xxh+WSO/FqKUxm/Ano8fCWd2T3IA2J4GFFmVElLOkyYu92Dw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:20:40.231692Z","signed_message":"canonical_sha256_bytes"},"source_id":"2308.16764","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3311df025f09c0fbd1c0982511f37b8f0f9e9263b4ff5d9f8942446e08751b72","sha256:246632b8e476131485a4fe2d57dae124a12a0788b17432bd63a488af8826b8e7"],"state_sha256":"03819fed4a9cf7871741ef5c0162e9b8c510cebd413070715bf616844e16bc42"}
