From both considerations, and assuming the black-hole nature for the compact object (i.e., its mass $>3\\rm{M}_{\\odot}$), the possible donor mass is $\\approx$0.5--$1.4\\rm{M}_{\\odot}$, the inclination is $\\approx{40}^\\circ$--$60^\\circ$ and the distance is $\\approx$8--12\\,kpc. The corresponding mass of the compact object is $\\approx$4--$11\\rm{M}_{\\odot}$. We then confirm a previous estimate that the t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.07803","kind":"arxiv","version":2},"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"}
