Parker Solar Probe Observations of Proton Core‐Beam Distributions in Heliospheric Current Sheet Region: Quasilinear Instability Analysis Combined With Collisional Relaxation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Parker Solar Probe has been proven as instrumental for the observation of young solar wind. During the encounters E‐07 and E‐08, PSP recorded the core plus beaming protons crossing the heliospheric current Sheet region. When the observed PSP data is plotted in the temperature ratio versus parallel beta space, it is found that the occurrence ...

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...

Statistical Study of Short Large‐Amplitude Magnetic Structures at Mars Observed by MAVEN

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a statistical study of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Martian foreshock using data from the Mars Atmosphere and Volatile Evolution (MAVEN) mission between 01 January 2015 and 31 December 2019. We have identified 21,008 SLAMS during this time interval and statistical results are presented on the SLAMS ...

Juno Observations of Large‐Scale Azimuthal Fields and Flows in Jupiter's Nightside Magnetosphere: Field‐Aligned Currents, Effective Ionospheric Pedersen Conductivity, and Power to Atmospheric Heating

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Using the methodology of Cowley et al. (https://doi.org/10.1029/2025JA033993), we employ ∼8 years of Juno azimuthal magnetic field data to derive colatitude profiles of Jupiter's nightside (17‐05 hr via midnight) ionospheric equatorward Pedersen current from near the magnetic pole to inner magnetosphere field lines at 18° colatitude, from ...

Radial Evolution of Interplanetary Shock Properties with Heliospheric Distance: Observations from Parker Solar Probe

The Astrophysical Journal Letters
We present a comprehensive analysis of 66 interplanetary shocks observed by the Parker Solar Probe between 2018 November and 2024 January. Among these, 33 events fulfilled the Rankine–Hugoniot (R-H) conditions, ensuring reliable asymptotic plasma ...
