Title: Spectral analysis of the plasma and magnetic fields at the edge of
the heliosphere using Voyager data




We propose to characterize the turbulence in the solar wind, heliosheath, and local interstellar medium. We are developing an advanced spectral analysis technique based on several independent data gap reconstruction methods. We consider a spectral result reliable if three of these independent analysis methods give the same answer. These techniques will be used to characterize the turbulence, in some regions for the first time and in some regions over a much larger frequency range (by orders of magnitude) than previously possible. In addition to the analysis of current data, this work will prepare the ground for the spectral analysis of LISM plasma data when V2 crosses the heliopause.
