    A team of astronomers finds clues on the magnetism of a new kind of M dwarf
    A team of astronomers led by ICE-CSIC analyzed for the first time a long radio-observation of a scallop-shell star in a pioneer study. The team observed the star using the Giant Metrewave Radio Telescope (GMRT) located in Pune (India), and related it to the photometric information from NASA’s Transiting Exoplanet Survey Satellite (TESS) and Las Cumbres Global Telescope Observatory. Scallop-shell stars are a recently discovered class of young M dwarfs.
