Dissipative Pulsar Magnetosphere [PDF]

Journal of Cosmology and Astroparticle Physics, 2008
Dissipative axisymmetric pulsar magnetosphere is calculated by a direct numerical simulation of the Strong-Field Electrodynamics equations. The magnetic separatrix disappears, it is replaced by a region of enhanced dissipation.

Global-scale magnetosphere convection driven by dayside magnetic reconnection [PDF]

Nature Communications
Plasma convection on a global scale is a fundamental feature of planetary magnetosphere. The Dungey cycle explains that steady-state convection within the closed part of the magnetosphere relies on magnetic reconnection in the nightside magnetospheric ...

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 ...

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.

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.

Is Our Understanding of Solar-Wind/Magnetosphere Coupling Satisfactory?

Frontiers in Astronomy and Space Sciences, 2021
An assessment of our physics-based understanding of solar-wind/magnetosphere coupling finds that the understanding is not complete. Solar-wind/magnetosphere coupling is foundational to magnetospheric physics and it is a key to comprehending and ...

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.

Reconsideration on the concept model of throat aurora

地球与行星物理论评, 2022
The solar wind-magnetosphere-ionosphere coupling driven by the solar wind is a systematic process that involves the buffering of magnetosheath and the response and feedback of magnetosphere and ionosphere.

Geomagnetic Kp Index and Planetary Magnetosphere Size Relationship: for Mercury and Jupiter During two Types of Geomagnetic Conditions

مجلة بغداد للعلوم, 2020
Kp index correlates with the many magnetosphere properties, which are used to measure the level of magnetic activity. In the solar system, the two different planets, Mercury with weak magnetic field and Jupiter with strong magnetic field, are selected ...
