Both heliophysics and planetary physics seek to understand the complex nature of the solar
wind's interaction with solar system obstacles like Earth's magnetosphere, the ionospheres …

Solar wind charge-exchange (SWCX) emission is present in every X-ray observation of an
astrophysical object. The emission is problematic when one cannot remove the foreground …

The soft X‐ray emissions from the Earth's magnetosheath and cusp regions are simulated
under different solar wind conditions, based on the PPMLR‐MHD code. The X‐ray images …

General methods for improving the specification of electron precipitation in global
simulations are described and implemented in the Lyon‐Fedder‐Mobarry (LFM) global …

The numerical results from a physics‐based global magnetohydrodynamic (MHD) model are
used to examine the effect of the interplanetary magnetic field (IMF), solar wind dynamic …

This chapter reviews recent findings of multi‐scale structures and dynamics in the high‐
latitude ionosphere, particularly on meso‐scale (10s‐100s km) processes, as well as their …

We describe a coupled geospace model that includes causally regulated ion outflow from a
physics‐based ionosphere/polar wind model. The model two‐way couples the multifluid …

We investigate the influence of the interplanetary magnetic field (IMF) clock angle ϕimf on
high‐latitude inertial Alfvén wave (IAW) activity in the magnetosphere‐ionosphere transition …

We present a case study of the Magnetospheric Multiscale (MMS) observations of the
Southern Hemispheric dayside magnetospheric boundaries under southward interplanetary …

Ionospheric electrodynamics is a problem of mechanical stress balance mediated by
electromagnetic forces. Joule heating (the total rate of frictional heating of thermospheric …
