SH21D-2531: Voyager Informed Modeling of Pickup Ions and Energetic Neutral Atoms
Interstellar Boundary Explorer (IBEX), a NASA spacecraft measuring neutral atoms coming from the edge of our solar system, observed an excess of neutral atom fluxes at certain energies. Normally, large-scale computer models of the whole heliosphere, the protective bubble that surrounds the solar system, are used to recreate IBEX observations, but those models don’t always match what the Voyager spacecraft has observed. In this study, we calculate neutral atom fluxes based on data from Voyager 2 only, without using large-scale models. Despite the efforts, the predicted neutral atom fluxes still cannot fully explain IBEX observations, though possible reasons for the gap is being explored.
