A global analysis of the system shows that the host star is an evolved subgiant star with $T_{\\rm eff} = 5370\\pm51$ K, $M_{*} = 1.438_{-0.052}^{+0.061} M_{\\odot}$, $R_{*} = 2.72_{-0.17}^{+0.21} R_{\\odot}$, log $g_*= 3.727_{-0.046}^{+0.040}$, and [Fe/H]$ = 0.180\\pm0.075$. The planet is a low-mass gas giant in a $P = 4.736529\\pm0.00006$ day orbit, with $M_{P} = 0.195\\pm0.018 M_J$, $R_{P}= 1.37_{-0.12}^{+0.15} R_J$, $\\rho_{P} = 0.093_{-0.024}^{+0.028}$ g cm$^{-3}$, surface gravity log ${g"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.01755","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"}
