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…

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…

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…

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…

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…
