Local Interstellar Flow Parameters from the First Intersection of IMAP-Lo's Parameter Tubes
Nathan A. Schwadron, Mitchell M. Shen, Fatemeh Rahmanifard +24
The Sun's motion through the interstellar medium creates a flow of interstellar neutral (ISN) atoms through the heliosphere. ISN He, due to its high universal abundance and relativ…
Review of Machine Learning Models for Solar Energetic Particle Prediction
Spiridon Kasapis, Pouya Hosseinzadeh, Kathryn Whitman +73
Solar energetic particle (SEP) events have attracted increasing attention due to their significant radiation hazards for aviation, spacecraft electronics, and human missions beyond…
Constraining Electron-Impact Ionization of O Through UV Aurora Observations at Ganymede
Stefan Duling, Joachim Saur, Darrell Strobel +3
While photoionization rates of Ganymede's O dominated atmosphere are well constrained, the contribution of electron-impact ionization is rather uncertain. Previous quantitative…
Auroral Acceleration Generates Electron Beams in Jupiter's Middle Magnetosphere
June Piasecki, Joachim Saur, George Clark +3
Observations made by the Juno spacecraft above Jupiter's polar regions have revealed that electrons accelerated toward Jupiter, which contribute to auroral emissions, are frequentl…
A Comparison of Geminid Models with the PSP/WISPR-observed Phaethon Dust Trail
Karl Battams, Galina O. Ryabova, Angel J. Gutarra-Leon +3
White-light observations from the WISPR instrument on NASA's Parker Solar Probe recently revealed the presence of a narrow, dense dust trail close to the orbit of asteroid 3200 Pha…
A Rotational Disruption Crisis for Zodiacal Dust
Kedron Silsbee, Brandon S. Hensley, Jamey R. Szalay +2
A systematic torque from anisotropic radiation can rapidly spin up irregular grains to the point of breakup. We apply the standard theory of rotational disruption from radiative to…
Global Heliospheric Termination Shock Strength in the Solar-Interstellar Interaction
E. J. Zirnstein, R. Kumar, B. L. Shrestha +4
A heliospheric termination shock (HTS) surrounds our solar system at approximately 100 astronomical units from the Sun, where the expanding solar wind (SW) is compressed and heated…
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…
Corotation-bounce resonance of ions in Jupiter's magnetosphere
Y. Sarkango, J. R. Szalay, P. A. Damiano +6
Banded energy distributions of H, O, S, and O or S ions between 100 eV to ~20 keV are consistently observed in Jupiter's magnetosphere mapping to M-…
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…
Size distribution of small grains in the inner zodiacal cloud
J. R. Szalay, P. Pokorný, D. M. Malaspina
The Parker Solar Probe (PSP) spacecraft has transited the inner-most regions of the zodiacal cloud and detects impacts to the spacecraft body via its electric field instrument. Mul…
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…
Parker Solar Probe Observations of Energetic Particles in the Flank of a Coronal Mass Ejection Close to the Sun
N. A. Schwadron, Stuart D. Bale, J. Bonnell +32
We present an event observed by Parker Solar Probe at 0.2 au on March 2, 2022 in which imaging and \emph{in situ} measurements coincide. During this event, PSP passed through…
Properties of electrons accelerated by the Ganymede-magnetosphere interaction: survey of Juno high-latitude observations
J. Rabia, V. Hue, N. Andre +16
The encounter between the Jovian co-rotating plasma and Ganymede gives rise to electromagnetic waves that propagate along the magnetic field lines and accelerate particles by reson…
Mass supply from Io to Jupiter's magnetosphere
L. Roth, A. Blöcker, K. de Kleer +24
Since the Voyager mission flybys in 1979, we have known the moon Io to be both volcanically active and the main source of plasma in the vast magnetosphere of Jupiter. Material lost…
