Particle tomography of the inner magnetosphere [PDF]

open access: yesJournal 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 ...

Response of convection electric fields in the magnetosphere to IMF orientation change [PDF]

open access: yes, 2009
[1] The transient response of convection electric fields in the inner magnetosphere to southward turning of the interplanetary magnetic field (IMF) is investigated using in‐situ electric field observations by the CRRES and Akebono spacecraft.

Saturation Characteristics of Parallel EMIC Waves in the Inner Magnetosphere

open access: yesGeophysical Research Letters, 2019
In this letter, detailed evolution process of parallel electromagnetic ion cyclotron waves in the inner magnetosphere has been investigated through quasilinear theory. A new saturation has been found to occur after the usual first saturation.

Progress in understanding the inner magnetosphere [PDF]

open access: yesEos, Transactions American Geophysical Union, 2012
Inner Magnetosphere Coupling 2; Los Angeles, California, 19–22 March 2012 Solar activity can energize Earth's magnetosphere. Coupled plasma interactions—involving multiscale electromagnetic fields, currents, and waves—either dissipate this energy into the ionosphere (to influence upper atmospheric chemistry and possibly climate) or store it in belts of

Butterfly pitch-angle distribution of relativistic electrons in the outer radiation belt: Evidence of nonadiabatic scattering [PDF]

open access: yes, 2015
In this paper we investigate the scattering of relativistic electrons in the nightside outer radiation belt (around the geostationary orbit). We consider the particular case of low geomagnetic activity (|Dst|\u3c20 nT), quiet conditions in the solar wind,

Erosion of the inner magnetosphere during geomagnetic storms [PDF]

open access: yesAnnales Geophysicae, 1997
Using the empirical magnetic field model dependent on the Dst index and solar wind dynamic pressure, we calculated the behaviour of the contour B = Bs in the equatorial plane of the magnetosphere where Bs is the magnetic field in the subsolar point ...

Propeller outflows from an MRI disc [PDF]

open access: yes, 2013
We present the results of axisymmetric simulations of MRI-driven accretion onto a rapidly rotating, magnetized star accreting in the propeller regime.

The role of the Hall effect in the global structure and dynamics of planetary magnetospheres: Ganymede as a case study [PDF]

open access: yes, 2015
We present high resolution Hall MHD simulations of Ganymede's magnetosphere demonstrating that Hall electric fields in ion-scale magnetic reconnection layers have significant global effects not captured in resistive MHD simulations. Consistent with local

Equatorial electron density measurements in Saturn's inner magnetosphere [PDF]

open access: yesGeophysical Research Letters, 2005
Upper hybrid resonance emissions detected by the Radio and Plasma Wave Science (RPWS) instrument on the Cassini spacecraft are used to obtain electron densities on five equatorial orbits of Saturn at radial distances ranging from 3 to 9 saturnian radii (RS).

Storm time dynamics of ring current protons: Implications for the long‐term energy budget in the inner magnetosphere

open access: yesGeophysical Research Letters, 2016
Our investigation of the long‐term ring current proton pressure evolution in Earth's inner magnetosphere based on Van Allen Probes data shows drastically different behavior of the low‐ and high‐ energy components of the ring current proton population ...
