  • M dwarfs harbour stellar dynamos driven by convective motions in their interiors. Previously, the magnetic field strengths generated by these dynamos were thought to saturate at 4 kG, but this limit has now been busted by four stars with dipole dynamo states.

  • Cool white dwarf stars often have mysteriously strong magnetic fields (because their coolness suggests that they are old, and magnetic fields should decline in strength with age) and unexplained brightness variations; here the magnetic field is shown to suppress atmospheric convection, inhibiting cooling evolution and causing dark spots.
