Kinetic Structure of an Interplanetary Shock Observed at Two Heliocentric Longitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Collisionless shocks convert bulk flow energy into heat, electromagnetic fields, and non‐thermal particle populations. Recent studies suggest that downstream magnetic oscillations could play an important role in ion‐scale energy dissipation at low‐Mach‐number shocks; however, the specific shock and plasma parameters involved remain poorly ...

Investigating the Role of Inward Alfvén Waves and Structures in the Slow Solar Wind

The Astrophysical Journal
The solar wind dynamics are thought to be governed by counter-propagating Alfvén waves. Alfvén waves generate a turbulent cascade through nonlinear couplings between shearing wave packets. However, imbalances, structures, and intermittency complicate the

Galileo PLS Plasma Observations During the E12 Europa Flyby Refuting an Encounter With a Cryovolcanic Plume

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

Distribution of equatorial Alfvén velocity in the magnetosphere: a statistical analysis of THEMIS observations

Earth, Planets and Space, 2018
It has been known that the Alfvén velocity plays a significant role in generation and propagation of magnetohydrodynamic (MHD) waves. Until now, however, the global distribution of the Alfvén velocity in the magnetosphere has not been reported.

Non-WKB Models of the FIP Effect: The Role of Slow Mode Waves

, 2011
A model for element abundance fractionation between the solar chromosphere and corona is further developed. The ponderomotive force due to Alfven waves propagating through, or reflecting from the chromosphere in solar conditions generally accelerates ...

Differences in Ultra‐Low‐Frequency Waves Associated With Dipolarization in the Near‐Earth Magnetotail Between Substorms and Pseudosubstorms

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We studied the characteristics of ultra‐low‐frequency (ULF) waves associated with dipolarization in the near‐Earth plasma sheet for substorms and pseudosubstorms, employing superposed epoch analysis of data from the Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft.

Roles of Fast-Cyclotron and Alfven-Cyclotron Waves for the Multi-Ion Solar Wind

, 2012
Using linear Vlasov theory of plasma waves and quasi-linear theory of resonant wave-particle interaction, the dispersion relations and the electromagnetic field fluctuations of fast and Alfven waves are studied for a low-beta multi-ion plasma in the ...
