QUOTE `{}`	We observed the β Pic system with the MeerKAT array on four occasions in 2025 and 2026, in the L band (0.8–1.7 GHz) and S band (1.7–3.5 GHz).
QUOTE `{}`	The emission from β Pic b is composed of recurring, rapidly-variable bursts with large circular polarization of ≈40–70%, as well as fainter inter-burst persistent emission. The remaining epochs (2025-02-15 L-band; 2026-02-20 S-band low &...
QUOTE `{}`	The burst detected in the S-band is also the most circularly polarized (≈70%) and is detected up to 3.5 GHz, the top of the observing band, therefore requiring a magnetic field of B≳1.25 kG at the emission site.
