Soft X‐Ray Emission From Saturn's Magnetosheath Part I: 3D Modeling From MHD Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosheath hosts a mixed population of water‐group neutrals and solar wind plasma. We present a 3‐D model of soft X‐ray emission by ion‐neutral charge exchange in the near‐equatorial magnetosheath. The model employs MHD simulation data of plasma properties at Saturn, Enceladus‐genic neutral populations extrapolated from existing ...

Variable structure model for flow-induced tonal noise control with plasma actuators

, 2008
The objective of this work was to study the effect of plasma actuators in attenuating low-speed flow-induced cavitytones from a control point of view by employing techniques from classical control. A modification of the existingphysics-based linear model

Propagation of cosmic rays through a plasma [PDF]

, 1978
The theory of the coupling of energetic particles to a plasma by Alfven wave instabilities is described. The theory is applied to the problem of propagation of cosmic rays through the interstellar plasma and to the problem of trapping of cosmic rays in ...

The May 2024 Superstorm Coronal Mass Ejections as Observed by the Psyche Gamma‐Ray and Neutron Spectrometer

Space Weather, Volume 24, Issue 5, May 2026.
Abstract We report new measurements of high‐energy protons ejected by the sun during the May 2024 Ganon superstorm. Our observations were made by the Neutron Spectrometer (NS) on the Psyche spacecraft, which was located at a solar distance of approximately 2 AU and a Sun‐Earth‐Probe separation angle of 75°.

Survival of 2D Turbulence in the Local Interstellar Medium

The Astrophysical Journal Letters
The evolution of 2D turbulence in the partially ionized local interstellar medium is investigated using 2D MHD simulations coupled with a neutral hydrogen gas via charge exchange.

A two-component transport model for solar wind fluctuations: Waves plus quasi-2D turbulence [PDF]

, 2010
We present a model for the transport of solar wind fluctuations, based on the assumption that they can be well-represented using two distinct components: a quasi-2D turbulence piece and a wave-like piece.

Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

Collective Plasma Phenomena and their Role in the Dynamics of the Interstellar Medium [PDF]

Symposium - International Astronomical Union, 1970
The First Symposium on cosmical gas dynamics clearly demonstrated that magnetic fields play an essential role in the dynamics of the interstellar matter. The Symposium emphasized that the behavior of interstellar gas should be described not by traditional gas dynamics but with the help of magneto-gas dynamics.

Two-component model of the interaction of an interstellar cloud with surrounding hot plasma

, 2011
International audienceWe present a two-component gasdynamic model of an interstellar cloud embedded in hot plasma. It is assumed that the cloud consists of atomic hydrogen gas, and that the interstellar plasma is quasi-neutral.
