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…
Energy-dependent SEP Fe/O abundances during the May 2024 superstorm
G. D. Muro, C. M. S. Cohen, Z. Xu +16
During mid-May 2024, active region (AR) 13664 produced a series of M- and X-class flares along with several coronal mass ejections (CMEs) that resulted in exceptionally strong auro…
Radial dependence of ion fluences in the 2023 July 17 SEP event from Parker Solar Probe to STEREO and ACE
G. D. Muro, C. M. S Cohen, Z. Xu +18
In the latter moments of 17 July 2023, the solar active region 13363, near the southwestern face of the Sun, was undergoing considerable evolution, which resulted in a significant…
Comparing Methods for Calculating Solar Energetic Particle Intensities: Re-binning versus Spectral Binning
M. E. Cuesta, L. Y. Khoo, G. Livadiotis +13
Solar energetic particle (SEP) events have been observed for decades in the interplanetary medium by spacecraft measuring the intensity of energetic ions and electrons. These inten…
Diverse dust populations in the near-Sun environment characterized by PSP/ISIS
M. M. Shen, J. R. Szalay, P. Pokorný +9
The Integrated Science Investigation of the Sun (ISIS) energetic particle instrument suite on Parker Solar Probe is dedicated to measuring energetic ions and electrons in th…
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…
Magnetic reconnection-driven energization of protons up to 400 keV at the near-Sun heliospheric current sheet
M. I. Desai, J. F. Drake, T. Phan +22
We report observations of direct evidence of energetic protons being accelerated above ~400 keV within the reconnection exhaust of a heliospheric current sheet (HCS) crossing by NA…
Observations of Kappa Distributions in Solar Energetic Protons and Derived Thermodynamic Properties
M. E. Cuesta, A. T. Cummings, G. Livadiotis +13
In this paper we model the high-energy tail of observed solar energetic proton energy distributions with a kappa distribution function. We employ a technique for deriving the therm…
Kappa-tail technique: Modeling and application to Solar Energetic Particles observed by Parker Solar Probe
G. Livadiotis, A. T. Cummings, M. E. Cuesta +10
We develop the kappa-tail fitting technique, which analyzes observations of power-law tails of distributions and energy-flux spectra and connects them to theoretical modeling of ka…
