"Insights from Heavy Ion Composition in the Heliosphere"

Abstract:

While they make up a small fraction of the material in the heliosphere, measurements of elements heavier than helium can reveal critical information about their origin from the Sun, planets, small solar system bodies, and the interstellar medium. These measurements also inform us about the processes involved in particle acceleration and transport throughout the solar system. Spaceborne ion mass spectrometers can be used to sample this material in-situ throughout the heliosphere, and when combined with remote sensing measurements and models can unlock a detailed understanding of the physical processes at work in the solar system. My talk will review scientific insights gained through the study of solar wind heavy ion composition and discuss future directions for research.
