Abstract:Magnetic fields are extremely rare in close, hot binaries, with only 1.5% of such systems known to contain a magnetic star. The eccentric ε Lupi system stands out in this population as the only close binary in which both stars are known to be magnetic. We report the discovery of strong, variable radio emission from ε Lupi using the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope. The light curve exhibits striking, unique characteristics including sharp, high-amplitude pulses th… Show more
