Fact check
“The detected radio signals are caused by magnetic activity.”
Reasoning
The provided articles report that the radio signals detected by the MeerKAT telescope are interpreted by the study's authors as arising from intense magnetic activity on the young, massive exoplanet Beta Pictoris b. The articles quote the authors' reasoning that charged particles trapped in a strong magnetic field produce the observed radio waves, and that the signal characteristics align with theoretical models of planetary magnetic fields. No contradictory evidence is presented in the supplied sources.
On confidence: Multiple primary sources (WIRED articles) cite the authors' interpretation that the radio emissions match theoretical predictions for magnetic activity in the exoplanet.
Important context
The study is a preprint and has not yet undergone peer review, so the interpretation remains provisional, but the claim that the signals are caused by magnetic activity is directly supported by the authors' analysis as reported in the sources.

Limitations
The assessment relies solely on the WIRED coverage of the preprint; no independent peer‑reviewed confirmation is available, and the articles do not provide raw data or detailed methodological critique.
