The Earth's magnetotail is an extremely complex system which—energized by the solar wind—
displays many phenomena, and Alfvén waves are essential to its dynamics. While Alfvén …

We use magnetometer chains collaborating with SuperMAG to derive SME, a generalization
of the auroral electrojet indices calculated from 100 or more sites instead of the 12 used in …

Shear mode Alfvén waves are the carriers of field-aligned currents in the auroral zones of
Earth and other planets. These waves travel along the magnetic field lines, coupling the …

We have developed an auroral precipitation model which separately categorizes the
discrete aurora and both the electron and ion diffuse aurora. The discrete aurora includes …

Magnetospheric substorms explosively release solar wind energy previously stored in
Earth's magnetotail, encompassing the entire magnetosphere and producing spectacular …

Jupiter displays the most powerful auroral emissions in our solar system, which result from
strong energy dissipation in Jupiter's surrounding space environment. Although mass and …

While the aurora has attracted attention for millennia, important questions remain
unanswered. Foremost is how auroral electrons are accelerated before colliding with the …

The sawtooth mode of convection of Earth's magnetosphere is a 2-to 4-hour planetary-scale
oscillation powered by the solar wind–magnetosphere–ionosphere (SW-MI) interaction …

Turbulence plays a key role in the conversion of the energy of large-scale fields and flows to
plasma heat, impacting the macroscopic evolution of the heliosphere and other …

It is demonstrated from observations that the Alfvénic aurora may be powered by a turbulent
cascade transverse to the geomagnetic field from large MHD scales to small Alfvén wave …
