Plasma turbulence in the interstellar medium [PDF]

Plasma Physics and Controlled Fusion, 2019
Abstract The interstellar medium (ISM) is a multi-phase, magnetized, and highly turbulent medium. In this paper, we address both theoretical and observational aspects of plasma turbulence in the ISM. We successively consider radio wave propagation through a plasma and radio polarized emission.

Plasma generation and processing of interstellar carbonaceous dust analogs [PDF]

Plasma Sources Science and Technology, 2018
Abstract Interstellar (IS) dust analogs, based on amorphous hydrogenated carbon (a-C:H) were generated by plasma deposition in radio frequency discharges of CH 4  + He mixtures.

Technology requirements of exploration beyond Neptune by solar sail propulsion [PDF]

, 2010
This paper provides a set of requirements for the technology development of a solar sail propelled Interstellar Heliopause Probe mission. The mission is placed in the context of other outer solar systems missions, ranging from a Kuiper Belt mission ...

Interplanetary and interstellar plasma turbulence [PDF]

Plasma Physics and Controlled Fusion, 2007
Theoretical approaches to low-frequency magnetized turbulence in collisionless and weakly collisional astrophysical plasmas are reviewed. The proper starting point for an analytical description of these plasmas is kinetic theory, not fluid equations. The anisotropy of the turbulence is used to systematically derive a series of reduced analytical models.

A Mesofractal Model of Interstellar Cloudiness

Universe, 2022
The interstellar medium (ISM), serving as a background for the propagation of cosmic rays (CRs) and other information carriers, has a complex ragged structure.

DYNAMIC SPECTRAL MAPPING OF INTERSTELLAR PLASMA LENSES [PDF]

The Astrophysical Journal, 2016
ABSTRACT Compact radio sources sometimes exhibit intervals of large, rapid changes in their flux density, due to lensing by interstellar plasma crossing the line of sight. A novel survey program has made it possible to discover these “Extreme Scattering Events” (ESEs) in real time, resulting in a high-quality dynamic spectrum of an ESE ...

Plasmoid Instability in the Multiphase Interstellar Medium

The Astrophysical Journal Letters, 2023
The processes controlling the complex clump structure, phase distribution, and magnetic field geometry that develop across a broad range of scales in the turbulent interstellar medium (ISM) remain unclear.

Future Exploration of the Outer Heliosphere and Very Local Interstellar Medium by Interstellar Probe. [PDF]

, 2023
A detailed overview of the knowledge gaps in our understanding of the heliospheric interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided along with predictions of with the scientific discoveries that await.

Compressible Magnetohydrodynamic Turbulence in Interstellar Plasmas [PDF]

The Astrophysical Journal, 2001
Radio wave scintillation observations reveal a nearly Kolmogorov spectrum of density fluctuations in the ionized interstellar medium. Although this density spectrum is suggestive of turbulence, no theory relevant to its interpretation exists. We calculate the density spectrum in turbulent magnetized plasmas by extending the theory of incompressible ...

Interstellar Scintillation and Clouds of the Interstellar Turbulent Plasma [PDF]

International Astronomical Union Colloquium, 2001
AbstractData on interstellar diffraction and refraction scintillation of pulsars are analyzed. Comparison between theory and the observational data shows that two types of spectra for electron density fluctuations are realized in the interstellar medium: pure power law and piecewise with a break. The distribution of turbulent plasma in the Galaxy has a
