Density turbulence in the outer heliosphere
- Density turbulence in the outer heliosphere was investigated using standard Fourier analyses of data from the Voyager-2 spacecraft, resulting in a new model for the level and spectral index of density turbulence as a function of heliocentric distance and direct evidence for interstellar pickup ions driving enhanced turbulence in the outer heliosphere [Cairns et al., 2001].
