The magnetic fields of cool bodies beyond the Solar System.
Very small stars, and also “brown dwarfs”, the balls of gas that are between stars and planets in size, have magnetic fields that are quite similar to the ones we find planets around Earth and Jupiter — they’re just hundreds of times stronger! These magnetic fields drive a rich phenomenology of space plasma physics and tell us about the internal structure of these bodies.
