Solar-Terrestrial Physics, 2022 In this paper, we study parameters of geomagnetic pulsations in the 1–4 mHz frequency range (Pc5/Pi3) in the magnetotail, utilizing data obtained by Cluster satellites at different levels of fluctuations in the interplanetary magnetic field (IMF) and the

ULF Waves Modulating and Acting as Mass Spectrometer for Dayside Ionospheric Outflow Ions
Geophysical Research Letters, 2019 Ionospheric outflow has been shown to be a dominant ion source of Earth's magnetosphere. However, most studies in the literature are about ionospheric outflow injected into the nightside magnetosphere.

Magnetosphere-Ionosphere Coupling: Implications of Non-Equilibrium Conditions
Frontiers in Astronomy and Space Sciences, 2022 The response times of the coupled magnetosphere-ionosphere-thermosphere system are, on average, greater than the autocorrelation timescales of solar wind forcing. This means that the system is rarely, if ever, in equilibrium.

Turbulence in the Magnetospheres of the Outer Planets [PDF]
arXiv, 2021 The magnetospheres of the outer planets exhibit turbulent phenomena in an environment which is qualitatively different compared to the solar wind or the interstellar medium. The key differences are the finite sizes of the magnetospheres limited by their physical boundaries, the presence of a strong planetary background magnetic field and spatially very

Energy Transport by Kelvin-Helmholtz Instability at the Magnetopause
Fluids, 2019 By means of the formation of vortices in the nonlinear phase, the Kelvin Helmholtz instability is able to redistribute the flux of energy of the solar wind that flows parallel to the magnetopause. The energy transport associated with the Kelvin Helmholtz

The Triple Dusk-Dawn Aberration of the Solar Wind at Earth
Frontiers in Astronomy and Space Sciences, 2022 In this Brief Report it is pointed out that there are three dusk-dawn aberrations of the solar-wind plasma and magnetic structure approaching Earth and the magnitudes of these aberrations are estimated for various solar-wind types monitored from L1 ...

Magnetospheres of Terrestrial Exoplanets and Exomoons: Implications for Habitability and Detection [PDF]
The Astrophysical Journal Letters, Vol. 907, L45 (2021), 2020 Characterizing habitable exoplanets and/or their moons is of paramount importance. Here we show the results of our magnetic field topological modeling which demonstrate that terrestrial exoplanet-exomoon coupled magnetospheres work together to protect the early atmospheres of both the exoplanet and the exomoon.

Frontiers in Astronomy and Space Sciences, 2022 In this study we analyze the storm-time evolution of equatorial electron pitch angle distributions (PADs) in the outer radiation belt region using observations from the Magnetic Electron Ion Spectrometer (MagEIS) instrument aboard the Van Allen Probes in

MHD Simulations of Magnetospheric Accretion, Ejection and Plasma-field Interaction [PDF]
, 2013 We review recent axisymmetric and three-dimensional (3D) magnetohydrodynamic (MHD) numerical simulations of magnetospheric accretion, plasma-field interaction and outflows from the disk-magnetosphere boundary.

Kinetic Modeling of Magnetospheres [PDF]
, 2020 This paper presents the state of the art of kinetic modeling techniques for simulating plasma kinetic dynamics in magnetospheres. We describe the critical numerical techniques for enabling large-scale kinetic simulations of magnetospheres: parameter scaling, implicit Particle-in-Cell schemes, and fluid-kinetic coupling.
