Consequences of using nonlinear particle trajectories to compute spatial diffusion coefficients [PDF]

The propagation of charged particles through interstellar and interplanetary space has often been described as a random process in which the particles are scattered by ambient electromagnetic turbulence.

Two Pathways of Turbulent Energy Processing in Solar Wind Current Sheets: Confined Fragmentation versus Organized Transport

The Astrophysical Journal
Understanding how turbulent energy is dissipated in the heliosphere remains a central challenge in space plasma physics. While magnetic reconnection and other dissipative processes occurring within current sheets are widely regarded as leading channels ...

Anisotropic Heating and Cooling within Interplanetary Coronal Mass Ejection Sheath Plasma

Astrophysical Journal
This study presents the first comprehensive investigation of the relationship between heating and cooling, temperature anisotropy, turbulence level, and collisional age within interplanetary coronal mass ejection (ICME) sheaths, which are highly ...

Evolution of Solar Wind Turbulence during Radial Alignment of Parker Solar Probe and Solar Orbiter in 2022 December

The Astrophysical Journal Supplement Series
We investigate the radial evolution of solar wind turbulence during the radial alignment of Parker Solar Probe (PSP) and Solar Orbiter (SO) on 2022 December 10, with PSP located at approximately 0.11 au and SO near 0.88 au.

Modification of the turbulence properties at the bow shock: statistical results

Frontiers in Astronomy and Space Sciences
Turbulent solar wind is known to be a main driver of the processes inside the magnetosphere, including geomagnetic storms and substorms. Experimental studies of the last decade demonstrate additional ways of interplanetary plasma transport to the ...
