Ion Anisotropy in Earth's Magnetotail: Importance of High‐Energy Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The reconfiguration of the magnetotail current sheet during substorms often includes the formation of a thin current sheet (TCS) with a strong magnetic field line tension force. This force cannot be balanced by isotropic plasma pressure gradients, and force balance in such a TCS requires ion anisotropy and/or agyrotropy of plasma pressure.

Magnetism in the Brown Dwarf Regime [PDF]

, 2019
A suite of discoveries in the last two decades demonstrate that we are now at a point where incorporating magnetic behavior is key for advancing our ability to characterize substellar and planetary systems. The next decade heralds the exciting maturation

Jupiter's Auroral Ionosphere: Hybrid Monte Carlo, Auroral Spectrum and Conductivity Modeling

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a new model of auroral precipitation and associated phenomena at Jupiter, called the Jupiter Auroral Ionosphere Code (JAIC). The hybrid model follows the primary electron population using a Monte Carlo code that runs on a GPU, and computes the contribution of the secondaries using a two‐stream approximation.

Modelling the magnetosphere of Mercury [PDF]

A model magnetosphere for Mercury is presented using an upstream image-dipole and nightside 2-dimensional tail current sheet method. The tail field is represented by an analytical formulation.

A Simulation Study of an HFA-like Event at Mars

The Astrophysical Journal
Hot flow anomalies (HFAs) are transient structures at planetary bow shocks characterized by hot, tenuous plasma. At Mars, where no global dipole field exists, such events interact with the induced magnetosphere in a unique and poorly understood way. This

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.

Saturn’s Recurrent Auroral Flashes in the Equinoctial Campaign

The Astrophysical Journal
The past decades of Cassini’s investigation around Saturn have revealed the frequent occurrence of ∼1 hr quasiperiodic (QP) signatures in the in situ magnetic field and plasma measurements and plasma wave observations. Saturn’s aurora, as the response to

Comparative Dynamics of Substorms and Sawtooth Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a comprehensive comparative analysis of magnetospheric substorms and sawtooth events using multi‐point observations from ground‐based magnetometers, geostationary satellites, and the Time History of Events and Macroscale Interactions during Substorms mission.

Comparative studies of planetary magnetospheres

Eos, Transactions American Geophysical Union, 1992
Three recent “flyby” spacecraft encounters of planetary magnetospheres have provided new glimpses of the broad spectrum of plasma behaviors that occur within such environments. Voyager 2's encounter with Neptune in August 1989 and Galileo's grav itational assist encounters with Venus in February 1990 and Earth in December 1990 have revealed significant

Jupiter Data Analysis Program: Analysis of Voyager wideband plasma wave observations [PDF]

Voyager plasma wave wideband frames from the Jovian encounters are analyzed. The 511 frames which were analyzed were chosen on the basis of low-rate spectrum analyzer data from the plasma wave receiver.
