Description

In-situ measurements and remote-sensing observations have revealed a rich variety of activities in the solar atmosphere and wind, spanning over a huge amount of time and length scales. In this presentation we will focus on two main basic processes which have an important role in the energetics of the solar wind: (1) the turbulent energy transfer of the electromagnetic and kinetic energy with this correlation to magnetic reconnection processes, (2) and the role of the ambipolar electric field and Coulomb collisions in the acceleration of the solar wind and in shaping the electric velocity distribution functions hence in regulating its heat flux. In this context we will present some results form observations and comparisons with high-resolution fluid and kinetic numerical simulations.
