We detected X-ray pulsations and found the pulsation period $P\\approx 48.6$ ms, and its derivative $\\dot{P}\\approx 8.6\\times 10^{-14}$, twice larger than the previously reported values. The pulsar exhibits two very narrow (FWHM $\\sim 1.2$ ms) X-ray pulses each rotation, separated by $\\approx 0.48$ of the period, with a pulsed fraction of $\\approx 0.8$. Using the correct values of $P$ and $\\dot{P}$, we calculate the pulsar's spin-down power $\\dot{E}=3.0 \\times 10^{37}$ erg s$^{-1}$ "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.2349","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"}
