Radio bursts reportedly traced to exoplanet β Pictoris b
A post sharing an arXiv paper describes rapid, recurring radio bursts and persistent emission at 0.85–3.5 GHz from β Pictoris b.
TLDR
A post sharing an arXiv paper says MeerKAT traced auroral radio bursts to β Pictoris b rather than its star, calling it the first radio emission localized to an exoplanet. It says the emission mechanism implies a magnetic field of about 1.25 kilogauss or stronger at the source and describes this as the first direct magnetic-field strength measurement for a world beyond the Solar System.
