Within the Local Volume $( D < 11 ~\\rm Mpc)$ we derived the mean stellar density $\\Omega_*= 0.44\\%$ in the critical density units and the mean total matter density $\\Omega_m = 0.17$. In the sphere with a radius of 40 Mpc these quantities drop to $\\Omega_* = 0.24 - 0.32\\%$ and $\\Omega_m = 0.09 - 0.14$. In a larger volume within $D\\sim135$ Mpc the discussed densities become more uncertain: $\\Omega_* = 0.20 - 0.24\\%$ and $\\Omega_m ="},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.06326","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
