Magnetosphere-Ionosphere Coupling: Implications of Non-Equilibrium Conditions [PDF]

Frontiers in Astronomy and Space Sciences, 2022
The response times of the coupled magnetosphere-ionosphere-thermosphere system are, on average, greater than the autocorrelation timescales of solar wind forcing. This means that the system is rarely, if ever, in equilibrium.

Global current systems in the magnetosphere of Mercury [PDF]

Nature Communications
The global current systems of a planet represent electrodynamic interactions between its different parts, and between its magnetosphere and the ambient solar wind.

Asymmetric distribution of reconnection jet fronts in the Jovian nightside magnetosphere [PDF]

, 2013
Magnetic reconnection plays important roles in mass transport and energy conversion in planetary magnetospheres. It is considered that transient reconnection causes localized auroral arcs or spots in the Jovian magnetosphere, by analogy to the case in ...

The magnetosphere under weak solar wind forcing [PDF]

, 2007
The Earth's magnetosphere was very strongly disturbed during the passage of the strong shock and the following interacting ejecta on 21–25 October 2001. These disturbances included two intense storms (Dst*≈−250 and −180 nT, respectively).

Controlling of merging electric field and IMF magnitude on storm-time changes in thermospheric mass density [PDF]

Annales Geophysicae, 2013
The controls of merging electrical field, Em, and IMF (interplanetary magnetic field) magnitude, B, on the storm-time changes in upper thermospheric mass density are statistically investigated using GRACE accelerometer observations and the OMNI data ...

Azimuthal magnetic fields in saturn's magnetosphere: Effects associated with plasma sub-corotation and the magnetopause-tail current system [PDF]

, 2003
We calculate the azimuthal magnetic fields expected to be present in Saturn’s magnetosphere associated with two physical effects, and compare them with the fields observed during the flybys of the two Voyager spacecraft.

Observations of a Mini‐Magnetosphere Above the Martian Crustal Magnetic Fields

Geophysical Research Letters, 2023
Mars is typically regarded as a non‐magnetic planet. Currents in the Martian ionosphere generate a Venus‐like induced magnetosphere which deflects the solar wind flows and piles up the interplanetary magnetic fields.

Juno Plasma Wave Observations at Ganymede

Geophysical Research Letters, 2022
The Juno Waves instrument measured plasma waves associated with Ganymede's magnetosphere during its flyby on 7 June, day 158, 2021. Three distinct regions were identified including a wake, and nightside and dayside regions in the magnetosphere ...

Next generation magnetic field measurements from low-earth orbit satellites enable enhanced space weather operations

Frontiers in Astronomy and Space Sciences, 2022
Large-scale current systems in the ionosphere and the magnetosphere are intimately controlled by the solar wind-magnetosphere interaction and the magnetosphere-ionosphere coupling.

Inner southern magnetosphere observation of Mercury via SERENA ion sensors in BepiColombo mission

Nature Communications, 2022
Mercury’s southern inner magnetosphere is an unexplored region as it was not observed by earlier space missions. In October 2021, BepiColombo mission has passed through this region during its first Mercury flyby.
