Counterintuitive Magnetic Connectivity and Energetic Particle Flux Differences among Nearby Spacecraft During the 2023 February 24 Solar Energetic Particle Event
Weihao Liu, Xianyu Liu, David Lario +4
For solar energetic particles (SEPs), it is generally expected that observers magnetically closer to the eruption source region exhibit higher particle intensities than those poorl…
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…
Shock properties for solar energetic particle events with signatures of inverse velocity arrival
A. Kouloumvakos, D. Lario, G. M. Mason +20
We present a detailed investigation of the shock properties associated with solar energetic particle (SEP) events that exhibit a concave (``nose-like'') shape in their energy spect…
Compressive Structures in the Foreshock of Collisionless Shocks
Savvas Raptis, Domenico Trotta, Drew L. Turner +11
Collisionless shocks are fundamental accelerators of energetic particles; yet, the observations of nonlinear foreshock structures, which are essential in acceleration processes, di…
Parker Solar Probe observations of solar energetic particle (SEP) events with inverse velocity arrival (IVA) features
Zigong Xu, C. M. S. Cohen, R. A. Leske +21
In SEP events, velocity dispersion (VD) is characterized by the earlier arrival of faster, higher-energy particles relative to slower ones, assuming negligible acceleration time an…
Solar Energetic Proton Events Observed by the High Energy Telescopes on the STEREO Spacecraft or at the Earth During the First Solar Orbit of STEREO A (2006 to 2023)
Ian G. Richardson, Tycho T. von Rosenvinge, O. Chris St. Cyr +3
The twin STEREO A and B spacecraft were launched in October 2006 into heliocentric orbits at around 1 AU, advancing ahead of or lagging behind Earth, respectively, at around 22 deg…
Solar Eruption Onset and Particle Acceleration in Nested-Null Topologies
Pankaj Kumar, Judith T. Karpen, Peter F. Wyper +3
The magnetic breakout model explains a variety of solar eruptions, ranging from small-scale jets to large-scale coronal mass ejections (CMEs). Most of our previous studies are focu…
CoSEE-Cat: A Comprehensive Solar Energetic Electron event Catalogue obtained from combined in situ and remote-sensing observations from Solar Orbiter -- Catalogue description and first statistical results
A. Warmuth, F. Schuller, R. Gómez-Herrero +39
(abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs…
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,…
Physics-Based Simulation of the 2013 April 11 Solar Energetic Particle Event
Weihao Liu, Igor V. Sokolov, Lulu Zhao +11
Solar energetic particles (SEPs) can pose hazardous radiation risks to both humans and spacecraft electronics in space. Numerical modeling based on first principles offers valuable…
Shock and SEP Modeling Study for the 5 September 2022 SEP Event
A. Kouloumvakos, N. Wijsen, I. C. Jebaraj +10
On September 5, 2022, during Parker Solar Probe's (PSP) 13th encounter, a fast shock wave and a related solar energetic particle (SEP) event were observed as the spacecraft approac…
An Overview of Solar Orbiter Observations of Interplanetary Shocks in Solar Cycle 25
D. Trotta, A. Dimmock, H. Hietala +17
Interplanetary shocks are fundamental constituents of the heliosphere, where they form as a result of solar activity. We use previously unavailable measurements of interplanetary s…
Improved modelling of SEP event onset within the WSA-Enlil-SEPMOD framework
Erika Palmerio, Janet G. Luhmann, M. Leila Mays +14
Multi-spacecraft observations of solar energetic particle (SEP) events not only enable a deeper understanding and development of particle acceleration and transport theories, but a…
On the Mesoscale Structure of CMEs at Mercury's Orbit: BepiColombo and Parker Solar Probe Observations
Erika Palmerio, Fernando Carcaboso, Leng Ying Khoo +27
On 2022 February 15, an impressive filament eruption was observed off the solar eastern limb from three remote-sensing viewpoints, namely Earth, STEREO-A, and Solar Orbiter. In add…
