Measuring the electric fields in space

open access: yes地球与行星物理论评, 2021
Measuring electric fields in the space environments of the Earth and other planets helps us to understand the electric field structures and plasma waves in the space.

Magnetospheres of Terrestrial Exoplanets and Exomoons: Implications for Habitability and Detection [PDF]

open access: yesThe Astrophysical Journal Letters, Vol. 907, L45 (2021), 2020
Characterizing habitable exoplanets and/or their moons is of paramount importance. Here we show the results of our magnetic field topological modeling which demonstrate that terrestrial exoplanet-exomoon coupled magnetospheres work together to protect the early atmospheres of both the exoplanet and the exomoon.

AB INITIO PULSAR MAGNETOSPHERE: THREE-DIMENSIONAL PARTICLE-IN-CELL SIMULATIONS OF OBLIQUE PULSARS [PDF]

open access: yes, 2014
We present “first-principles” relativistic particle-in-cell simulations of the oblique pulsar magnetosphere with pair formation. The magnetosphere starts to form with particles extracted from the surface of the neutron star.

Parameters of current systems in the magnetosphere as derived from observations of cosmic rays during the June 2015 magnetic storm

open access: yesSolar-Terrestrial Physics, 2017
Basing on measurements of cosmic rays at the worldwide network of stations, we calculate variations in the planetary system of geomagnetic cutoff rigidity for the 2015 June moderate geomagnetic storm.

Observational research on Mercury's magnetosphere

open access: yes地球与行星物理论评, 2021
Mercury's miniature magnetosphere has no radiation belts, ionosphere, plasmasphere and atmosphere, only a weak exosphere. The induction effect of the planet's very large iron core is obvious. These result in a significant different space environment from

Effects of electrojet turbulence on a magnetosphere‐ionosphere simulation of a geomagnetic storm

open access: yes, 2017
Ionospheric conductance plays an important role in regulating the response of the magnetosphere‐ionosphere system to solar wind driving. Typically, models of magnetosphere‐ionosphere coupling include changes to ionospheric conductance driven by extreme ...

ELECTRODYNAMICS OF AXISYMMETRIC PULSAR MAGNETOSPHERE WITH ELECTRON–POSITRON DISCHARGE: A NUMERICAL EXPERIMENT [PDF]

open access: yes, 2014
We present the first self-consistent global simulations of pulsar magnetospheres with operating e± discharge. We focus on the simple configuration of an aligned or anti-aligned rotator.

ULF fluctuations at Terra Nova Bay (Antarctica)

open access: yesAnnals of Geophysics, 2000
ULF geomagnetic field measurements in Antarctica are a very important tool for better understanding the dynamics of the Earth’s magnetosphere and its response to the variable solar wind conditions.

Ion acceleration at dipolarization fronts in the inner magnetosphere

open access: yes, 2017
During geomagnetic storms plasma pressure in the inner magnetosphere is controlled by energetic ions of tens to hundreds of keV. Plasma pressure is the source of global storm time currents, which control the distribution of magnetic field and couple the ...
