Two articles – one published in the journal “Nature Astronomy” and one published in “The Astrophysical Journal Letters” – report different aspects of the discovery of radio wave emissions from 19 red dwarfs of which at least 4 could have originated from interaction with unknown planets. This study is based on detections obtained with the LOFAR radio telescope to examine the stellar magnetic activity of 19 red dwarfs. Radio emissions have also been detected from ancient and magnetically inactive stars. Data collected by NASA’s TESS space telescope was also added to get a more complete picture of that activity. The most likely explanation is that there’s an interaction with the magnetic field of planets that haven’t been detected.
