Solar Wind Acceleration and Heating
Abstract
The heating of the solar corona and acceleration of the solar wind represent one of the fundamental problems in all of space science. While different scenarios have been proposed to explain the heating of magnetically confined and open regions of the corona, they all rely on the transfer, storage and dissipation of the abundant free energy present in photospheric convection. In this talk I will focus specifically on models involving Alfvén waves which lead to the solar wind as observed at 1 AU, discussing the difficulties in deriving consistently both wave- spectrum evolution and solar wind distribution functions. Using the example of reflection driven Alfvénic turbulence in coronal holes and the solar wind, I will describe which kinds of measurements are most likely to help advance our understanding of this crucial problem.
