Influence Of Upstream Solar Wind On Magnetic Field Distribution In The Martian Nightside Ionosphere
This study is led by Postdoctoral researcher Jiawei Gao from IGGCAS. Unlike Earth, Mars lacks a global dipolar magnetic field; the planet does have locally distributed crustal magnetic fields.

Magnetic Fields of M Dwarfs from the Pleiades Open Cluster
Average magnetic field measurements are presented for 62 M-dwarf members of the Pleiades open cluster, derived from Zeeman-enhanced Fe I lines in the H-band. An MCMC methodology was employed to […]

MHD Simulations of the Space Weather in Proxima b: Habitability Conditions and Radio Emission
The habitability of exoplanets hosted by M-dwarf stars dramatically depends on their space weather. We present 3D magneto-hydrodynamic simulations to characterise the magneto-plasma environment and thus the habitability of the […]

Removal Of Magnetic Spacecraft Contamination Within Extraterrestrial Samples Is Easy To Do
For decades, scientists have pondered the mystery of the moon’s ancient magnetism. Based on analyses of lunar samples, its now-deceased magnetic field may have been active for more than 1.5 […]

Properties of Electrons Accelerated by the Ganymede-magnetosphere Interaction: Survey of Juno High-latitude Observations
The encounter between the Jovian co-rotating plasma and Ganymede gives rise to electromagnetic waves that propagate along the magnetic field lines and accelerate particles by resonant or non-resonant wave-particle interaction. […]

Exoplanet Magnetic Fields
Planetary magnetic fields are important indicators of planetary processes and evolution, from a planet’s outer core to its surface (if it possesses one) to its atmosphere and near-space environment.
