Frontiers in Astronomy and Space Sciences, 2022 It is often assumed that on average, polar ionospheric electrodynamics in the Northern and Southern Hemispheres are mirror symmetric or antisymmetric with respect to the interplanetary magnetic field By component and the dipole tilt angle ψ. For example,

Near-Approach Imaging Simulation of Low-Altitude ENA Emissions by a LEO Satellite
Frontiers in Astronomy and Space Sciences, 2020 We simulate a 2-D ENA coded modulation imager on board a polar orbit satellite. An imaging measurement, which can realize continuous monitoring of low-altitude ENA emission sources, is applied to the evolution process of energetic ion events. The present

Noise and solar-wind/magnetosphere coupling studies: Data
Frontiers in Astronomy and Space Sciences, 2022 Using artificial data sets it was earlier demonstrated that noise in solar-wind variables alters the functional form of best-fit solar-wind driver functions (coupling functions) of geomagnetic activity.

STATISTICAL PROPERTIES OF AURORAL KILOMETER RADIATION: BASED ON ERG (ARASE) SATELLITE DATA
Solar-Terrestrial Physics, 2021 In this work, we have studied the signals of auroral kilometer radiation (AKR) from sources in the auroral regions of the Northern and Southern hemispheres simultaneously recorded by one satellite.

The Earth’s Magnetosphere: A Systems Science Overview and Assessment
Surveys in geophysics, 2018 A systems science examination of the Earth’s fully interconnected dynamic magnetosphere is presented. Here the magnetospheric system (a.k.a. the magnetosphere–ionosphere–thermosphere system) is considered to be comprised of 14 interconnected subsystems ...

Magnetospheric Mass Density as Determined by ULF Wave Analysis
Frontiers in Astronomy and Space Sciences, 2021 The technique to estimate the mass density in the magnetosphere using the physical properties of observed magnetohydrodynamic waves is known as magnetoseismology.

How the IMF By induces a By component in the closed magnetosphere and how it leads to asymmetric currents and convection patterns in the two hemispheres [PDF]
, 2015 We used the Lyon‐Fedder‐Mobarry global magnetohydrodynamics model to study the effects of the interplanetary magnetic field (IMF) By component on the coupling between the solar wind and magnetosphere‐ionosphere system.

Generation of high-energy particles, neutrino and fotons in magnetosphere of collapsing star
EPJ Web of Conferences, 2014 The generation of particles, photons and neutrinos in magnetosphere of collapsing star are considered. These processes are caused the self-interaction initial accelerating in magnetosphere protons and electrons.
