Title: Equilibrium velocity distributions in parallel propagating low-frequency Alfvenic turbulence

Abstract

The equilibrium velocity distributions in parallel propagating, circularly polarized low-frequency Alfvenic turbulence are presented. The equilibrium solutions of the monochromatic Alfven waves are extended to those of incompressible Alfvenic turbulence with the broadband spectrum in low beta plasmas. It is shown that the ''apparent temperature'' due to the nonresonant ion heating is explained on the basis of the equilibrium velocity distribution. The anisotropic equilibrium velocity distribution corresponding to Alfvenic turbulence in the Chew-Goldberger-Low system is also demonstrated. It is suggested that the distribution can be the back ground structure in the asymmetric velocity distributions observed in the solar wind.
