Effect of Turbulence on Transport SEPs in the Heliosphere

Solar energetic particles (SEPs) are high-energy particles originating from the Sun and accelerated at the front of a CME-driven shock. They pose potential risks to space missions, especially those outside Earth's protective magnetosphere. Understanding their behavior in both the heliosphere and Earth's magnetosphere is vital for the safety and functionality of space exploration. The study focuses on how pitch angle scattering impacts the overall SEP population during various phases of SEP events.

Incorporating pitch angle scattering effects at these extended distances is essential for a comprehensive understanding of SEP event decay dynamics. This modeling of SEPs is further integrated with simulations of other critical space phenomena, including the solar wind, interplanetary magnetic field, and Alfvén wave turbulence. This presentation details the modeling techniques employed in this research and explores the impact of pitch angle scattering at various heliocentric distances on the SEP events' decay phase dynamics.
