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 ...

Magnetic Discontinuities in the Inner Heliosphere: Do Intermediate Shocks Exist?
The Astrophysical Journal, 2023 Magnetic discontinuities are fundamental structures in space and laboratory plasmas where the changes in magnetic and velocity fields are constrained by Rankine–Hugoniot relations.

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 ...

Acceleration of an interplanetary shock through the magnetosheath: a global hybrid simulation
Frontiers in Astronomy and Space SciencesAccording to most observations and simulations, interplanetary shocks slow down when they propagate through the magnetosheath. In this article, we present results from a self-consistent global hybrid PIC simulation of an interplanetary shock which, by ...

Impact angle control of interplanetary shock geoeffectiveness [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractWe use Open Geospace General Circulation Model global MHD simulations to study the nightside magnetospheric, magnetotail, and ionospheric responses to interplanetary (IP) fast forward shocks. Three cases are presented in this study: two inclined oblique shocks, hereafter IOS‐1 and IOS‐2, where the latter has a Mach number twice stronger than ...

Electron Heating in 2D Particle-in-cell Simulations of Quasi-perpendicular Low-beta Shocks
The Astrophysical JournalWe measure the thermal electron energization in 1D and 2D particle-in-cell simulations of quasi-perpendicular, low-beta ( β _p = 0.25) collisionless ion–electron shocks with mass ratio m _i / m _e = 200, fast Mach number ${{ \mathcal M }}_{\mathrm{ms}}=1$
