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

Properties of Ion Upflows in the Low‐Altitude Polar Ionosphere During CIR‐ and CME‐ Driven Magnetic Storms Based on Long‐Term EISCAT Observations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We have investigated the effects of Corotating Interaction Region‐ (CIR‐) and Coronal Mass Ejection‐ (CME‐) driven magnetic storms on the characteristics and mechanisms of ion upflow in the low‐altitude ionosphere (250–350 km). Our analysis was based on observations from the European Incoherent Scatter (EISCAT) radars at Tromsø (ILAT = ∼66 ...

Ultralow-frequency Waves in Jupiter’s Magnetopause Boundary Layer

The Astrophysical Journal
Ultralow-frequency (ULF) waves (∼tens of minutes period) are widely identified in the Jovian system and are believed to be associated with energy dissipation in the magnetosphere and ionosphere.

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.

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two

Double Layers in the Martian Magnetosheath

The Astrophysical Journal
The observation of electrostatic double layers in Martian magnetosheath plasma is reported, based on medium-frequency (100 Hz–32 kHz) electric field data recorded by the Langmuir Probe and Waves on board the Mars Atmosphere and Volatile Evolution ...

Multiple‐Event Study of Substorm Electric Field Penetration Into Middle Latitudes Based on Simultaneous Observation of 630‐nm Airglow Enhancements at Three Stations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract It is known that convection electric fields develop in the polar region associated with substorm onset, and a westward electric field penetrates to lower latitudes on the night side. Two‐dimensional observations of 630‐nm airglow enhancements associated with the westward electric field can be conducted using all‐sky cameras at middle latitudes.
