Implications of Kappa Suprathermal Halo of the Solar Wind Electrons
Original language description
Based on a large data set of electron velocity distribution functions measured in situ in the solar wind plasma, we have a statistical analysis of main non-thermal characteristics with respect to macroscopic properties of electrons, i.e., number density, bulk velocity, temperature and temperature anisotropy. The analysis indicates that the properties exhibit interdependence trends characterized by correlations between certain of these macroscopic parameters and the kappa exponent corresponding to the power law model function of the non-thermal population. The links between low kappa and low number densities confirm that Coulomb collisions can be quite ineffective even at low radial distances if the density of the plasma is sufficiently low. Moreover, non-thermal populations with lower values of κ parameter are also associated to higher temperature anisotropies, and to higher bulk velocity. Finally the κ parameter is discussed in terms of solar wind modelling with using the so-called exospheric approach.
