A Dynamic Auroral Ionospheric Density Profile Reveals a Planetary-Scale Cavity at Jupiter [PDF]
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract Low‐altitude measurements above Jupiter's main auroras have shown the presence of persistent auroral density depletions. This low density regime strongly favors auroral acceleration by inertial Alfvén waves to explain the predominance of energetic (100–1,000 keV) broadband electron beams.

Geophysical Monograph Series, Page i-xiv., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

An Ultra-Compact Ion Mass Spectrometer for Observations of Planetary Ionospheres [PDF]
, 2023 The Compact Ion Mass Spectrometer (CIMS) is an ultra-low resource ion mass spectrometer being designed to make observations of low-energy space plasmas such as that in planetary ionospheres. The CIMS utilizes a laminated collimator to define the field-of-

Perspective on Energetic and Thermal Atmospheric Photoelectrons
Frontiers in Astronomy and Space Sciences, 2021 Atmospheric photoelectrons are central to the production of planetary ionospheres. They are created by photoionization of the neutral planetary atmosphere by solar EUV and soft X-ray irradiance.

Ion Loss within a Reconnection Exhaust near Mars: MAVEN Observations
The Astrophysical Journal, 2023 We present observations from Mars Atmosphere and Volatile EvolutioN of a reconnection exhaust, which was probably not ongoing, in the Martian magnetosheath. The reconnection jet with abundant heavy ions is directed outward to space.

Long extra-tropical planetary wave propagation in the presence of slowly varying mean flow and bottom topography. II: ray propagation and comparison with observations [PDF]
, 2003 Ray theory is used to predict phase and group velocities for long planetary waves under realistic, albeit slowly varying, oceanic conditions. The results are compared with local theory using fields smoothed to the same amount (9° latitude/longitude) as ...
