Evidence of flare and coronal mass ejection-driven shock acceleration of relativistic protons on 21 November 2024
M. Jarry, A. Papaioannou, G. Vasalos +9
On 21 November 2024 at 17:55 UTC, a solar flare erupted from far-side active region (AR) 13892, with enhanced hard X-ray flux measured by Solar Orbiter (SO). It was associated with…
Delayed maximum energy solar energetic particle events: Statistical analysis from Solar Orbiter
R. C. Allen, G. C. Ho, G. M. Mason +9
Investigations of solar energetic particles (SEPs) have long utilized the dispersive nature of onset times, as in, the earlier arrival of higher-energy particles compared to lower-…
Wave-Growth-Limited Particle Confinement in a Near-Parallel Interplanetary Shock Observed by Parker Solar Probe
A. Kouloumvakos, I. C. Jebaraj, M. A. Malkov +11
Collisionless shocks confine the particles they accelerate with the upstream wave field they themselves drive. Streaming particles resonantly amplify Alfvén waves, and the waves th…
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…
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…
On the reason for the widespread energetic storm particle event of 13 March 2023
N. Dresing, I. C. Jebaraj, N. Wijsen +20
On 13 March 2023, when the Parker Solar Probe was situated on the far side of the Sun as seen from Earth, a large solar eruption took place creating a strong solar energetic partic…
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…
Composition variation of the May 16 2023 Solar Energetic Particle Event observed by Solar Orbiter and Parker Solar Probe
Z. G. Xu, C. M. S Cohen, R. A. Leske +13
In this study, we employ the combined charged particle measurements from Integrated Science Investigation of the Sun (\ISOIS) onboard the Parker Solar Probe (PSP) and Energetic Par…
Direct Measurements of Synchrotron-Emitting Electrons at Near-Sun Shocks
I. C. Jebaraj, O. V. Agapitov, M. Gedalin +22
In this study, we present the first-ever direct measurements of synchrotron-emitting heliospheric traveling shocks, intercepted by the Parker Solar Probe (PSP) during its close enc…
Solar energetic particles injected inside and outside a magnetic cloud: The widespread solar energetic particle event on 2022 January 20
L. Rodríguez-García, R. Gómez-Herrero, N. Dresing +22
Context. On 2022 January 20, the Energetic Particle Detector (EPD) on board Solar Orbiter measured a solar energetic particle (SEP) event showing unusual first arriving particles f…
