Energetic Particle Acceleration and Transport: Interplanetary Coronal Mass Ejections and Shocks
Olga E. Malandraki, Christina M. S. Cohen, Joe Giacalone +16
Solar Energetic Particles from suprathermal (few keV) up to relativistic (few GeV) energies constitute an important contributor to the characterization of the space environment. Em…
Probing Solar Wind Structures with Solar Energetic Particle Observations from Solar Orbiter
Xiaohang Chen, Gang Li, Joe Giacalone +12
The propagation of solar energetic particles (SEPs) through the heliosphere is primarily guided by the interplanetary magnetic field (IMF) which is embedded in the solar wind plasm…
Radial Dependency of ICME-associated Particle Acceleration Processes: Statistical Multipoint Observations from 2016-2023
Malik H. Walker, Robert C. Allen, George C. Ho +6
During the propagation of interplanetary coronal mass ejections (ICMEs), evolution of the ICME-driven shock along with interactions with other solar wind structures, planetary bodi…
Sunward Streaming 3He-rich SEP Events Observed by Solar Orbiter and Parker Solar Probe during Perihelion Passage
Samuel T. Hart, George C. Ho, Michael R. Terres +7
We report on two 3He-rich solar energetic particle (SEP) events observed by Solar Orbiter (SO) and Parker Solar Probe (PSP) during the April 1 - 4, 2024 conjunction when both space…
Local Particle Acceleration in an ICME-in-Sheath Structure Observed by Solar Orbiter
Xiaomin Chen, Chuan Li, Zigong Xu +5
Local particle acceleration in the shock sheath region formed during the interaction between multiple coronal mass ejections (CMEs) is a complicated process that is still under inv…
Bidirectional anisotropic solar energetic particle events observed by Solar Orbiter
Zheyi Ding, Robert F. Wimmer-Schweingruber, Yu Chen +12
Solar Energetic Particle (SEP) events are critical for understanding particle acceleration and transport in the heliosphere. While most SEP events involve outward streaming particl…
A Tale of Two Shocks
Robert F. Wimmer-Schweingruber, Domenico Trotta, Rungployphan Kieokaew +23
Energetic particles in interplanetary space are normally measured at time scales that are long compared to the ion gyroperiod. Such observations by necessity average out the microp…
Evidence of Time-Dependent Diffusive Shock Acceleration in the 2022 September 5 Solar Energetic Particle Event
Xiaohang Chen, Lulu Zhao, Joe Giacalone +15
On 2022 September 5, a large solar energetic particle (SEP) event was detected by Parker Solar Probe (PSP) and Solar Orbiter (SolO), at heliocentric distances of 0.07 and 0.71 au,…
Investigation of Inverse Velocity Dispersion in a Solar Energetic Particle Event Observed by Solar Orbiter
Zheyi Ding, F. Robert Wimmer-Schweingruber, Alexander Kollhoff +15
Inverse velocity dispersion (IVD) events, characterized by higher-energy particles arriving later than lower-energy particles, challenge the classical understanding of SEP events a…
Radial Evolution of ICME-Associated Particle Acceleration Observed by Solar Orbiter and ACE
Malik H. Walker, Robert C. Allen, Gang Li +5
On 2022 March 10, a coronal mass ejection (CME) erupted from the Sun, resulting in Solar Orbiter observations at 0.45 au of both dispersive solar energetic particles arriving prior…
SEP environment in the inner heliosphere from Solar Orbiter and Parker Solar Probe
Robert F. Wimmer-Schweingruber, Javier Rodriguez-Pacheco, George C. Ho +4
The Sun drives a supersonic wind which inflates a giant plasma bubble in our very local interstellar neighborhood, the heliosphere. It is bathed in an extremely variable background…
Modelling two Energetic Storm Particle Events Observed by Solar Orbiter Using the Combined EUHFORIA and iPATH Models
Zheyi Ding, Gang Li, Glenn Mason +6
By coupling the EUropean Heliospheric FORcasting Information Asset (EUHFORIA) and the improved Particle Acceleration and Transport in the Heliosphere (iPATH) model, two energetic s…
