We detect... emission at frequencies of 0.85 to 3.5 GHz. We identify the emission as electron cyclotron maser radiation, which implies a magnetic field of ≳1.25 kG at the planet.",

The 1.25-kG value is a lower limit mapped from the highest detected frequency to the magnetic field at the emission site; the report is a 2026 arXiv preprint, so the claim should not imply a measured global surface field or peer-reviewed final result."
