A Closer Look at Small-scale Magnetic Flux Ropes in the Solar Wind at 1 au: Results from Improved Automated Detection

The Astrophysical Journal Supplement Series
Small-scale interplanetary magnetic flux ropes (SMFRs) are similar to ICMEs in magnetic structure, but are smaller and do not exhibit coronal mass ejection plasma signatures.

Regulation of Solar Wind Electron Temperature Anisotropy by Collisions and Instabilities

The Astrophysical Journal
Typical solar wind electrons are modeled as being composed of a dense but less energetic thermal “core” population plus a tenuous but energetic “halo” population with varying degrees of temperature anisotropies for both species.

The Energy Cascade Rate in Supersonic Magnetohydrodynamic Turbulence

The Astrophysical Journal
Three-dimensional direct numerical simulations are implemented to investigate the energy cascade rate in compressible isothermal magnetohydrodynamic turbulence. Utilizing an exact law derived from the Kármán–Howarth equation, we examine the contributions

Spatiotemporal Properties of Compressible Magnetohydrodynamic Turbulence from Space Plasma

The Astrophysical Journal
It is well established that Alfvénic turbulence undergoes a weak-to-strong transition as energy cascades to smaller scales, but whether this occurs in compressible magnetohydrodynamic (MHD) turbulence remains unclear.

Small-amplitude Compressible Magnetohydrodynamic Turbulence Modulated by Collisionless Damping in Earth’s Magnetosheath: Observation Matches Theory

The Astrophysical Journal
Plasma turbulence is a ubiquitous dynamical process that transfers energy across many spatial and temporal scales and affects energetic particle transport.

Formation of H+ PUI Tails Downstream of Distant Interplanetary Shocks

The Astrophysical Journal
New Horizons’ Solar Wind Around Pluto (SWAP) instrument has observed interplanetary shocks from ∼20 to 60 au from the Sun. Different studies have analyzed the effects of these shocks on the solar wind ion (SWI) and interstellar pickup ion (PUI ...
