Testing the Fidelity of Paleopole Determinations From Multidirectionally Magnetized Lunar Crustal Anomaly Source Bodies

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Inversions of satellite observations of the lunar crustal magnetic field do not consistently produce regional magnetization directions consistent with a selenocentric axial dipolar field. We modeled the thermal evolution of anomaly source bodies in the lunar crust and found that large features (impact melt sheets and ejecta deposits) cool ...

Thermospheric Density, Composition, and Temperature From GOES‐R/SUVI Solar Occultations

Space Weather, Volume 23, Issue 9, September 2025.
Abstract A new data set of atomic oxygen (O) and molecular nitrogen (N2 ${\mathrm{N}}_{2}$) number density profiles, along with thermospheric temperature profiles between 180 and 500 km, has been developed. These profiles are derived from solar occultation measurements made by the Solar Ultraviolet Imager (SUVI) on the GOES‐R satellites, using the 17.1,

Inversion of Global Thermospheric Density Map Based on Satellite Measurements Using Deep Learning RFR Network

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The estimation error of neutral mass density is a major source of uncertainty in calculating thermospheric drag, which is the primary non‐gravitational perturbation affecting satellites in low Earth orbit. Many empirical models and physics‐based models are commonly used to forecast the thermospheric density, but significant deviations might ...

Ferrimagnetic Structure of 3C Pyrrhotite (Fe7S8) From Neutron Diffraction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Pyrrhotite is a paleomagnetically important magnetic mineral in many geological settings. It forms numerous polytypes with different stacking patterns of the NiAs structure along the crystallographic c axis to produce different vacancy‐ordered superstructures.

Theory and Modeling of Large Scale Plasmapause Surface Waves

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The plasmapause in Earth's magnetosphere represents the boundary between the plasma which co‐rotates with the Earth (plasmasphere), and the more tenuous plasmatrough outside. The density change across the plasmapause can be large, changing by approximately 1–2 orders of magnitude depending on the prevailing conditions. This would suggest it to
