Dynamo Action in Late-type Giants

  title={Dynamo Action in Late-type Giants},
  author={S\oren Bertil F. Dorch},
Recent numerical MHD simulations suggest that magnetic activity may occur in late-type giants. A entire red supergiant with stellar parameters equal to Betelgeuse was modelled in 3d with the high-order " Pencil Code ". Linear kinematic and non-linear saturated dynamo action are found and the non-linear magnetic field saturates at a super-equipartition value… CONTINUE READING
