Cosmic-ray transport in the galactic magnetosphere [PDF]

It is advantageous to regard cosmic rays as the constitutent particles of the Galactic radiation belts and cosmic ray energization as a consequence of inward radial diffusion in the quasi-dipolar Galactic magnetosphere. This process occurs in addition to

Improving the Efficiency and Resolution of Time of Flight (TOF) Mass Spectrometer for Magnetospheric Applications. [PDF]

, 2016
The Earth magnetosphere is the volume of space formed by the Earth magnetic field in response to the flow of plasma from the solar wind. Although the magnetopause shields us from the solar wind there are far more particles that penetrate with energy, and

A model for nulling and mode changing in pulsars

, 2010
We propose that in some pulsars the magnetosphere has different states with different geometries or/and different distributions of currents, it occasionally switches between them.

Association of Relativistic Electron Microbursts Duration With Chorus Wave Properties

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Relativistic electron microbursts are correlated with resonant scattering by whistler‐mode chorus waves. Here, we use chorus wave properties obtained from Van Allen Probe A to calculate the duration of relativistic microbursts. A detailed quantitative comparison between observed and calculated microburst durations shows consistent ranges and ...

Twisted magnetosphere with quadrupolar fields in the exterior of a neutron star

, 2018
The magnetar magnetosphere is gradually twisted by shearing from footpoint motion, and stored magnetic energy also increases at the same time. When a state exceeds a threshold, flares/outbursts manifest themselves as a result of a catastrophic transition.

A Generation Mechanism of Banded Plasmaspheric Hiss

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract As a unique structure of plasmaspheric hiss emissions, banded hiss waves generally consist of an upper band above ∼200 Hz, a lower band below ∼100 Hz and a power gap in between. However, the generation mechanism of banded hiss remains unclear.

Magnetospheric consciousness

, 2014
This book belongs to a series of online books summarizing the recent state Topological Geometrodynamics (TGD) and its applications. TGD can be regarded as a unied theory of fundamental interactions but is not the kind of unied theory as so called GUTs constructed by graduate students at seventies and eighties using detailed recipes for how to reduce ...

Contribution of Substorm‐Injected Electrons to the High‐Frequency Plasmaspheric Hiss Generation: A Statistical Study by Van Allen Probes

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract High‐frequency plasmaspheric hiss (HFPH) is considered to be excited by substorm‐injected electrons in a case study (He et al., 2019, https://doi.org/10.1029/2018gl081578). To better understand its generation, we performed a statistical study on this wave and electron distributions, based on the Van Allen Probe data from 2012 to 2018. It shows

Water Reservoirs in the Lower Mantle Beneath Northeastern Asia

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Water in the mantle controls mantle convection and chemical transport processes within Earth's interior. However, whether the water in the lower mantle is primordial or recycled remains an open question. Here we report an electrical structure consisting of two stepped high‐conductivity anomalies crossing the 660‐km interface beneath ...

Empirical Functions for Highly Charged Ion Abundances in Solar Wind Charge Exchange Models: Addressing Post‐2011 ACE Data Limitations

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Upcoming imaging missions—NASA's LEXI and ESA/CAS's SMILE—will target solar wind charge exchange X‐ray (SWCX) emission from Earth's magnetosheath. This emission is generated by highly charged ions colliding with neutrals in Earth's exosphere.
