Voyager 1 Electron Densities in the Very Local Interstellar Medium to beyond 160 au
The Astrophysical Journal LettersThe two Voyager spacecraft have been exploring the interstellar medium beyond the heliopause since 2012 (Voyager 1) and 2018 (Voyager 2). Electron plasma oscillations and a quasi-thermal noise line at the electron plasma frequency have enabled the ...

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Extreme ultraviolet spectrum of a hot interstellar plasma
The Astrophysical Journal Supplement Series, 1978 The EUV (100-1000 A) spectrum of an optically thin plasma over the temperature range 100,000-10 million K is calculated, and the effects of free-free, free-bound, and two-photon continuum radiation are considered. The resulting spectra are presented in graphical form, with a separate tabulation of intensities for the emission lines.

Entropy Export and Chemical Reactions in Plasmas
Plasma Processes and Polymers, Volume 23, Issue 1, January 2026.In a non‐equilibrium plasma, energy is transferred to molecules by electron‐impact (1), collisions among excited molecules (2), and Joule heating (3). The entropy balance for this open system relates the energy available per molecule to changes in entropy, which determines plasma‐based gas conversion. ABSTRACT Is plasma truly a “fourth state of matter”?

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Scattering of Continuously Injected Pickup Ions of Oblique Pickup Angles in the Outer Heliosheath
The Astrophysical JournalPitch angle scattering of pickup ions (PUIs) in the outer heliosheath is studied using two-dimensional hybrid simulations, with the PUIs continuously injected at specified injection rates and pickup angles.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract The Latmos Test Particle (LaTeP) model is a steady‐state test particle code to investigate the solar wind charge exchange soft X‐ray emissions of the steady‐state Earth magnetosphere. In this study, we present the development of a new dynamic version (D‐LaTeP) extending the LaTeP model to adapt to time‐varying solar wind conditions.

Investigating Extreme Scattering Events by Volumetric Ray-tracing
The Astrophysical JournalExtreme scattering events (ESEs) are observed as dramatic (>50%) drops in flux density that occur over an extended period of weeks to months. Discrete plasma lensing structures are theorized to scatter the radio waves produced by distant sources such as ...
