MeerKAT

A new study exploring the heart of our Galaxy has identified 137 stars that shine in both radio waves and X-rays, providing a clearer picture of stellar magnetic activity. By combining data from the MeerKAT radio telescope and the eROSITA X-ray satellite, researchers tested the famous Güdel-Benz relation, which usually links a star's heat-driven X-rays to its high-energy radio flares. The findings reveal that many stars in the Galactic plane are actually 'noisier' in radio frequencies than ...
