Radio signals from nearby red dwarfs could come from yet unknown exoplanets

Astronomers looked at the nearby red dwarfs to analyze radio waves coming from them. In most cases they caught waves from magnetically active stars, which was no surprise, however 4 of the stars generating radio waves were not magnetic. In their newly published study the scientists propose the signals coming from yet unseen exoplanets. If confirmed, radio signals could become a new way for detecting exoplanets.

Red dwarf stars with strong magnetic fields are quite common. And so are planets, at least in our solar system. Interaction of stellar winds and planetary magnetic field can produce radio waves. The same or similar process can be responsible for detected radio signals mentioned in new study linked bellow.
