Description
Turbulence and magnetic field amplification in protoneutron stars are important for supernova explosions, their associated multimessenger signal as well as to determine the properties of the neutron stars in particular their rotation and magnetic field. They can be driven by different processes including convection, magnetorotational instability and the Tayler-Spruit dynamo and are sensitive to small scales unresolved by global models. I will present numerical simulations showing the development of the Tayler-Spruit dynamo and discuss its potential to explain the extremely strong magnetic field of magnetars.
