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

open access: yesNature 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 ...

Review of Mercury’s dynamic magnetosphere: Post-MESSENGER era and comparative magnetospheres [PDF]

open access: yesScience China. Earth Sciences, 2021
This review paper summarizes the research of Mercury’s magnetosphere in the Post-MESSENGER era and compares its dynamics to those in other planetary magnetospheres, especially to those in Earth’s magnetosphere.

Fast Radio Bursts from Reconnection in a Magnetar Magnetosphere [PDF]

open access: yesAstrophysical Journal, 2020
The nearly 100% linear polarization has been reported for a few fast radio bursts (FRBs). This finding places severe limits on the emission mechanism.

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

open access: yesAnnales 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 ...

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

open access: yesFrontiers 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 ...

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

open access: yesFrontiers 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.

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

open access: yesGeophysical 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.

Reconsideration on the concept model of throat aurora

open access: yes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.

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

open access: yesNature 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.

EVIDENCE OF THE EARTH’S INNER RADIATION BELTS DURING THE LOW SOLAR AND GEOMAGNETIC ACTIVITY OBTAINED WITH THE STEP-F INSTRUMENT [PDF]

open access: yesRadio Physics and Radio Astronomy, 2021
Purpose: The subject of research is the spatio-temporal charged particles in the Earth’s magnetosphere outside the South Atlantic magnetic Anomaly during the 11-year cycle of solar activity minimum.
