A turbulence-driven model for heating and acceleration of the fast wind in coronal holes

Mostrar todas las versiones(4)

A model is presented for generation of fast solar wind in coronal holes, relying on heating that is dominated by turbulent dissipation of MHD fluctuations transported upward in the solar atmosphere. Scale-separated transport equations include large-scale fields, transverse Alfvénic fluctuations, and...
