Magnetospheric Configuration with Magnetotail Current

Terrestrial, Atmospheric and Oceanic Sciences, 2000
Magnetospheric configuration with magneto tail current is studied on a two-dimensional formulation. The planar magnetic field is represented by an analytic function of a complex variable that represents points of the. Noon-midnight plane. In our treatment, which accounts for both-the Chapman-Ferraro magnetopause current and the magnetotail current, the

THE EFFECTS OF ENERGETIC TRAPPED PARTICLES ON MAGNETOSPHERIC MOTIONS AND IONOSPHERIC CURRENTS

, 1961
It is shown that the temporary distortion of a previously stable belt of energetic charged particles, trapped in the earth's magnetic Held, results in a system of ionospheric currents and magnetospheric motions.

3-D force-balanced magnetospheric configurations [PDF]

, 2003
International audienceThe knowledge of plasma pressure is essential for many physics applications in the magnetosphere, such as computing magnetospheric currents and deriving mag-netosphere-ionosphere coupling.

Field-aligned currents in the magnetosphere

Geofísica Internacional, 1991
Las corrientes alineadas con el campo en la magnetosfera fluyen en todas partes, no s6lo a altas 1"-titudes sino también a medianas y bajas. Sin embargo, su detecci6n con satcHites solo ha sido posible en la región por encima de las zonas aurorales. La existencia de estas corrientes a medianas y bajas latitudes se puede inferir de un análisis de los ...

Magnetospheric Current Systems and the Polar Cap Index

, 2022
The transpolar convection of plasma and embedded magnetic fields generated by the solar wind interaction with the magnetosphere can be characterized by the polar cap (PC) indices, PCN (North) and PCS (South). These indices are derived from polar magnetic variations and calibrated with respect to the solar wind merging electric field (coupling function),

Coordinated ground-based and Cluster observations of large amplitude global magnetospheric oscillations during a fast solar wind speed interval [PDF]

, 2002
We present magnetospheric observations of very large amplitude global scale ULF waves, from 9 and 10 December 2000 when the upstream solar wind speed exceeded 600 km/s.

Unusual profile variations in pulsar PSR J1022+1001 – Evidence for magnetospheric “return currents”?

, 2003
We report a detailed multi-frequency study of significant instabilities observed in the average pulse profile of the 16-millisecond pulsar PSR J1022+1001.

Determining the State of Jupiter’s Magnetosphere Using In Situ and Remote Sensing Observations

The Astrophysical Journal
While Jupiter’s magnetosphere is primarily governed by internal processes, variations in solar wind conditions can significantly modulate magnetospheric energy.

Estimating the Rate of Cessation of Magnetospheric Activity in AMPERE Field‐Aligned Currents

Geophysical Research Letters, 2018
The decay of magnetospheric activity when driving is turned off (to a minimum) was measured in total field‐aligned current estimates from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) project.

Why Doesn't the Observed Field‐Aligned Current Saturate With Increasing Interplanetary Electric Field?

Geophysical Research Letters
Theoretical studies indicate that electric potential saturation in a polar cap ionosphere is regulated by the limited reconnection rate at the magnetopause associated with field‐aligned currents (FACs), predicting the possible saturation of FACs under ...
