Turbulence and Polytropic Changes across Interplanetary Shocks Observed by the Parker Solar Probe
The Astrophysical Journal LettersInterplanetary shocks play a critical role in solar wind dynamics, influencing the properties of turbulence and thermodynamic processes. In this study, we statistically analyze changes in turbulence characteristics and polytropic indices across 37 quasi ...

Generation and evolution of interplanetary slow shocks [PDF]
Annales Geophysicae, 1996 It is well known that most MHD shocks observed within 1 AU are MHD fast shocks. Only a very limited number of MHD slow shocks are observed within 1 AU.

Ionospheric Scintillation Induced by Hot Flow Anomalies via Particle Precipitation
AGU Advances, Volume 7, Issue 7, October 2026.Abstract Ionospheric scintillation disrupts trans‐ionospheric radio signals and represents significant challenges for critical communication and navigation systems. Here we document that hot flow anomalies (HFAs), transient disturbances formed near Earth's bow shock, can contribute to scintillation near the cusp.

Shock waves propagation in the turbulent interplanetary plasma [PDF]
Advances in Space Research, 1996 AbstractEffect of turbulence on interplanetary shock waves propagation is considered. It is shown that background turbulence results in the additional shock wave deceleration which may be comparable with the deceleration due to plasma sweeping. The turbulent deceleration is connected with the energy losses due to the strong turbulence amplification ...

Editorial to the Special Issue “Propagation of Coronal Mass Ejections”
Universe, 2023 Coronal mass ejections (CMEs) and their associated shocks are one of the main drivers of heliosphere variability, causing both interplanetary and planetary perturbations [...]

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...

MHD waves at the pre-front of interplanetary shocks on September 6 and 7, 2017
Solar-Terrestrial PhysicsWe analyze strong space weather disturbances during first ten days of September 2017, using the geomagnetic Dst index, parameters of normals to interplanetary shock fronts, direct measurements of interplanetary magnetic field, solar wind, and cosmic ray ...

Characteristics of Solar Wind Density Depletions During Solar Cycles 23 and 24 [PDF]
Journal of Astronomy and Space Sciences, 2017 Solar wind density depletions are phenomena that solar wind density is rapidly decreased and keep the state. They are generally believed to be caused by the interplanetary (IP) shocks.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Ultra‐low frequency (ULF) waves with frequencies 10–140 s are a characteristic feature of the foreshock, playing important roles in transient formation, shock reformation, and particle acceleration. We utilize 23 years of Cluster data to map ULF wave power and compressibility in the vicinity of Earth's bow shock, combining Cluster data with ...

Velocity profiles of interplanetary shocks [PDF]
, 1983 The type 2 radio burst was identified as a shock propagating through solar corona. Radio emission from shocks travelling through the interplanetary (IP) medium was observed.
