Relation between magnetosonic waves and pitch angle anisotropy of warm protons

Frontiers in Astronomy and Space Sciences, 2022
In the past decade, many observations of transversely heated low energy protons were reported in the inner magnetosphere. Interestingly, most of the time heated protons were observed along with magnetosonic waves.

Pulsar Magnetosphere: Variation Priciple, Singularities, Estimate of Power [PDF]

, 2005
We formulate variation principle for force-free magnetosphere of an inclined pulsar: ${\cal E} +{\bf \Omega}\cdot {\bf M}$ ($\cal E$, ${\bf M}$ are electromagnetic energy and angular momentum, ${\bf \Omega}$ is the angular velocity of a star) is ...

Dynamics of the terrestrial radiation belts: a review of recent results during the VarSITI (Variability of the Sun and Its Terrestrial Impact) era, 2014–2018

Progress in Earth and Planetary Science, 2021
The Earth’s magnetosphere is region that is carved out by the solar wind as it flows past and interacts with the terrestrial magnetic field. The inner magnetosphere is the region that contains the plasmasphere, ring current, and the radiation belts all ...

Ring current dynamics in the Earth's inner magnetosphere

地球与行星物理论评, 2022
The terrestrial ring current, flowing near the equator at the altitude of 2 RE～7 RE, is one of the most significant electric current systems of the Earth's magnetosphere.

Empirical modeling of the quiet time nightside magnetosphere [PDF]

, 1994
Empirical modeling of plasma pressure and magnetic field for the quiet time nightside magnetosphere is investigated. Two models are constructed for this study. One model, referred to here as T89R, is basically the magnetic field model of Tsyganenko (1989)

Method for Approximating Field-Line Curves Using Ionospheric Observations of Energy-Variable Electron Beams Launched From Satellites

Frontiers in Astronomy and Space Sciences, 2019
Using electron beam accelerators attached to satellites in Earth orbit, it may be possible to measure arc length and curvature of field-lines in the inner magnetosphere if the accelerator is designed with the capability to vary the beam energy.

Low‐Energy (

Journal of Geophysical Research: Space Physics, 2019
The heavy ion component of the low‐energy (eV to hundreds of eV) ion population in the inner magnetosphere, also known as the O+ torus, is a crucial population for various aspects of magnetospheric dynamics.

Warps, bending and density waves excited by rotating magnetized stars: results of global 3D MHD simulations [PDF]

, 2013
We report results of the first global three-dimensional magnetohydrodynamic simulations of the waves excited in an accretion disc by a rotating star with a dipole magnetic field misaligned from the star's rotation axis (which is aligned with the disc ...

Particle tomography of the inner magnetosphere [PDF]

Journal of Geophysical Research: Space Physics, 2002
In a previous study we performed a statistical analysis of the geosynchronous plasma environment from measurements of the magnetospheric plasma analyzer instruments aboard the Los Alamos geosynchronous spacecraft. In that study the mean spin‐averaged particle fluxes were determined as a function of local time and Kp index, averaged over an entire year ...

Solar Energetic Proton Access to the Near‐Equatorial Inner Magnetosphere

Journal of Geophysical Research: Space Physics, 2020
In this study we examine the ability of protons of solar origin to access the near‐equatorial inner magnetosphere. Here we examine four distinct solar proton events from 20–200 MeV, concurrent with both quiet time and storm time conditions using proton ...
