Full Title: A trans-disciplinary approach for tracing the energy flow throughout the heliosphere
Abstract: Heliophysics is inherently interdisciplinary, connecting multiple sub-disciplines within the space sciences, to achieve an enhanced understanding of the way the Sun influences its surrounding space-environment. The uniting theme is energy transfer: how is it generated and where does it go? The subject of kinetic-scale wave-particle interactions is often studied independently from macroscale contexts.
In this talk, we first approach the problem within the framework of turbulent energy dissipation mechanisms. We overview what we have learned about the nature of energy transfer in the inner heliosphere as seen by Parker Solar Probe’s initial orbits around the Sun. Specifically, we present observations of asymmetric particle velocity distribution functions synchronous with electromagnetic fields measurements. We conclude with a discussion of generalizing the language of energy dynamics within the framework of mathematics, working toward a transdisciplinary approach to heliophysics.
