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…
Variability of interplanetary shock and associated energetic particle properties as a function of the time window around the shock
Kimberly Moreland, Maher Dayeh, Gang Li +3
We study the effect of sampling windows on derived shock and associated energetic storm particle (ESP) properties in 296 fast-forward interplanetary shocks using ACE measurements a…
Spherical Harmonic Representation of Energetic Neutral Atom Flux Components Observed by IBEX
P. Swaczyna, M. A. Dayeh, E. J. Zirnstein
The Interstellar Boundary Explorer (IBEX) images the heliosphere by observing energetic neutral atoms (ENAs). The IBEX-Hi instrument onboard IBEX provides full-sky maps of ENA flux…
On the seed population of solar energetic particles in the inner heliosphere
Nicolas Wijsen, Gang Li, Zheyi Ding +5
Particles measured in large gradual solar energetic particle (SEP) events are believed to be predominantly accelerated at shocks driven by coronal mass ejections (CMEs). Ion charge…
Estimation of turbulent heating of solar wind protons at 1AU
George Livadiotis, Maher A. Dayeh, Gary P. Zank
The paper presents a new method for deriving turbulent heating of the solar wind using plasma moments and magnetic field data. We develop the method and then apply it to compute th…
Modeling Transport of Energetic Particles in Corotating Interaction Region -- A case Study
Lulu Zhao, Gang Li, R. W. Ebert +5
We investigate energetic particle transport in Corotating Interaction Regions (CIRs) through a case study. The CIR event we study occurred on February and was observed…
Seven Years of Imaging the Global Heliosphere with IBEX
D. J. McComas, E. J. Zirnstein, M. Bzowski +12
The Interstellar Boundary Explorer (IBEX) has now operated in space for 7 years and returned nearly continuous observations that have led to scientific discoveries and reshaped our…
Spectral properties of large gradual solar energetic particle events - II -Systematic Q/M-dependence of heavy ion spectral breaks
M. I. Desai, G. M. Mason, M. A. Dayeh +7
We fit the 0.1-500 MeV/nucleon H-Fe spectra in 46 large SEP events surveyed by Desai et al. (2016) with the double power-law Band function to obtain a normalization constant,…
Global Numerical Modeling of Energetic Proton Acceleration in a Coronal Mass Ejection Traveling through the Solar Corona
Kamen A. Kozarev, Rebekah M. Evans, Nathan A. Schwadron +4
The acceleration of protons and electrons to high (sometimes GeV/nucleon) energies by solar phenomena is a key component of space weather. These solar energetic particle (SEP) even…
