Dissipative Pulsar Magnetosphere [PDF]
Journal of Cosmology and Astroparticle Physics, 2008 Dissipative axisymmetric pulsar magnetosphere is calculated by a direct numerical simulation of the Strong-Field Electrodynamics equations. The magnetic separatrix disappears, it is replaced by a region of enhanced dissipation.

High latitude magnetospheric topology and magnetospheric substorm [PDF]
Annales Geophysicae, 2009 Abstract. This study is focused on the problem of the localization of substorm expansion onset. In this context, the high latitude topology of transverse magnetospheric currents has been analyzed. This study has included the radial distribution of plasma pressure near noon, obtained using the THEMIS-B satellite data, the daytime compression of magnetic

Magnetic Field Gradient Across the Flank Magnetopause
Frontiers in Astronomy and Space Sciences, 2021 Magnetic pressure inside the magnetopause is usually balanced with a sum of thermal plasma and magnetic pressures on the magnetosheath side. However, observations reveal that the magnetosheath magnetic field can be frequently larger than that in the ...

Organization of the magnetosphere during substorms [PDF]
, 2011 The change in degree of organization of the magnetosphere during substorms is investigated by analyzing various geomagnetic indices, as well as interplanetary magnetic field z-component and solar wind flow speed.

The magnetosphere as a complex system [PDF]
Advances in Space Research, 2013 The magnetosphere is a complex system, with multi-scale spatio-temporal behavior. Self-organization is a possible solution to two seemingly contradicting observations: (a) the repeatable and coherent substorm phenomena, and, (b) the underlying self-similar turbulent behavior in the plasma sheet.

On strangelets in the magnetosphere [PDF]
Il Nuovo Cimento B, 1995 A short discussion is provided on the hypothesis of strange quark dust of low specific charge in the terrestrial magnetosphere. We suggest by means of rough estimates the possible existence of a strangelet belt in the magnetosphere.

On the Heating of AGN Magnetospheres [PDF]
Universe, 2021 The Langmuir–Landau-Centrifugal Drive (LLCD), which can effectively “convert” gravitational energy into particles, is explored as a driving mechanism responsible for the extreme thermal luminosity acquired by some active galactic nuclei (AGN). For this purpose, we consider equations governing the process of heating of AGN magnetospheres. In particular,

The Magnetospheric Trough [PDF]
, 1997 The authors review the history of the concepts of the magnetospheric cold-ion trough and hot-electron trough and conclude that the two regions are actually essentially the same. The magnetospheric trough may be viewed as a temporal state in the evolution of convecting flux tubes.

Geophysical Monograph Series, Page i-xiv., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Mission Concept to Determine the Magnetospheric Causes of Aurora
Frontiers in Astronomy and Space Sciences, 2020 Insufficiently accurate magnetic-field-line mapping between the aurora and the equatorial magnetosphere prevents us from determining the cause of many types of aurora.
