Abstract

Interstellar pick-up ion and solar wind spectra were measured with New Horizons/SWAP between 11 and 12 AU. We report on detailed fitting of these spectra. To perform the fitting, we have constructed an empirical model that includes interstellar pick-up ions as well as solar wind H+, solar wind He2+, and solar wind O6+. A fifth population is needed to complete the fitting; we use inner source pick-up protons. We find a correlation between the densities of the solar wind H+, and all other populations. The two strongest correlations are with the interstellar pick-up ions and the inner source pick-up ions. We discuss the correlation between solar wind and interstellar pick-up ion densities.
