Partially ionized plasmas are found across the Universe in many different astrophysical
environments. They constitute an essential ingredient of the solar atmosphere, molecular …

The year 2019 marks the 60th anniversary of the concept of radial diffusion in
magnetospheric research. This makes it one of the oldest research topics in radiation belt …

The spin of a single electron subject to a static magnetic field provides a natural two-level
system that is suitable for use as a quantum bit, the fundamental logical unit in a quantum …

The relatively high contrast between planetary and solar low-frequency radio emissions
suggests that the low-frequency radio range may be well adapted to the direct detection of …

The morphologies of the ultraviolet auroral emissions on the giant gas planets, Jupiter and
Saturn, have conveniently been described with combinations of a restricted number of basic …

This review covers the work of the three decades since the first spectroscopic identification
of the H 3+ molecular ion outside of the laboratory in 1988, in the auroral atmosphere of the …

The first extended series of observations of Saturn's auroral emissions, undertaken by the
Hubble Space Telescope in January 2004 in conjunction with measurements of the …

We propose a simple illustrative axisymmetric model of the plasma flows and currents that
occur in Saturn's polar ionosphere which are due to both internal magnetospheric plasma …

Stellar coronal activity has been shown to persist into the low-mass star regime, down to late
M-dwarf spectral types. However, there is now an accumulation of evidence suggesting that …

We investigate magnetic data showing the presence of field‐aligned magnetosphere‐
ionosphere coupling currents on 31 Cassini passes across Saturn's southern postmidnight …
