Ionospheric disturbances generated by different natural processes and by human activity in Earth plasma environment
ionosphere Earth plasma environment
2015/9/14
The magnetosphere-ionosphere-thermosphere subsystem is strongly coupled via the electric field, particle precipitation, heat flows and small scale interaction. Satellites in situ measurements and grou...
Assessment of space plasma effectsfor satellite applications:Working Group 2 overview
effectsfor Space plasma
2015/9/14
An important part of the tasks of Working Group 2 of the COST Action 271 «Assessment of space plasma effect for satellites applications» is the assessment of novel data sources for informati...
Space plasma effects on Earth-spaceand satellite-to-satellite communications:Working Group 4 overview
Earth-spaceand satellite-to-satellite Space plasma
2015/9/14
This paper summarizes the the activities carried out by Working Group 4 of COST 271 Action. The structure of this Working Group included four Working packages that were dealing with different aspects ...
Answers to some salient questions, which arise in quantum plasmas, are given. Starting from the Schr\"{o}dinger equation for a single particle it is demonstrated how the Wigner-Moyal equation can be ...

Fermi- and Plasma-Accelerations Cosmic Rays
2011/1/11
The generic acceleration model for ultra high energy cosmic rays, which has been introduced in {\tt 1006.5708 [astro-ph.HE]}, suggests various types of electromagnetic interactions between cosmic char...
Coronal Loops: Observations and Modeling of Confined Plasma
Coronal Loops Observations Confined Plasma
2011/1/13
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma. ...
Alfven seismic vibrations of crustal solid-state plasma in quaking paramagnetic neutron star
Alfven seismic vibrations paramagnetic neutron star
2010/11/11
Magneto-solid-mechanical model of two-component, core-crust, paramagnetic neutron star responding to quake-induced perturbation by differentially rotational, torsional, oscillations of crustal electro...
Damping of longitudinal magneto-acoustic oscillations in slowly varying coronal plasma
magnetohydrodynamics(MHD) - plasmas - Sun corona - waves
2010/11/15
We investigate the propagation of MHD waves in a homogenous, magnetized plasma in a weakly
stratified atmosphere, representing hot coronal loops. In most of earlier studies a time-independent equilib...
Magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma protoshock
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
The prompt emissions of gamma-ray bursts are seeded by radiating ultrarelativistic electrons. Internal shocks propagating through a jet launched by a stellar implosion, are expected to amplify the mag...
Analysis of Plasma and Field Conditions during Some Intensely Geoeffective Transient Solar/Interplanetary Disturbances of Solar Cycle 23
Earth geomagnetic storm Sun'solar and wind magnetosphere coupling
2010/9/17
The problem of solar wind–magnetosphere coupling is investigated for intense geomagnetic storms (Dst ≤ −100 nT) that occurred during solar cycle 23. For this purpose interplanetary plasma and fi...
Damping of Slow Magnetoacoustic Waves in an Inhomogeneous Coronal Plasma
Sun corona—active region—coronal loops—TRACE—MHD waves—heating
2010/9/16
We study the propagation and dissipation of slow magnetoacoustic waves in an inhomogeneous viscous coronal loop plasma permeated by uniform magnetic field. Only viscosity and thermal conductivity are ...
Analysis of beam plasma instability effects on incoherent scatter spectra
Ionosphere plasma
2017/3/22
Naturally Enhanced Ion Acoustic Lines (NEIALs)
detected with Incoherent Scatter Radars (ISRs) can be produced
by a Langmuir decay mechanism, triggered by a bump
on tail instability. A recent model ...
Interaction of plasma cloud with external electric field in lower ionosphere
plasma cloud lower ionosphere
2017/3/22
In the auroral lower-E and upper-D region of the
ionosphere, plasma clouds, such as sporadic-E layers and
meteor plasma trails, occur daily. Large-scale electric fields,
created by the magnetospher...
