Bianchi I Spacetimes in f(Q)‐Gravity

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT The Kasner spacetimes are exact solutions that are self‐similar and of significant interest because they can describe the dynamic evolution of kinematic variables near the singularity of the Mixmaster universe. The chaotic behavior of the Mixmaster universe is related to the Kasner relations.

Boundary‐Only Weak Deflection by Regular Black Holes, Black‐Bounces, Wormholes, and Static Quadrupolar Spacetimes

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

System Identification Based Models for Electron Fluxes Measured by GOES 16

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract System identification is employed to develop a set of models to forecast the electron fluxes at geostationary orbit. The energy of the electron fluxes are based on the measurements of (GOES 16) (MPS‐HI). The GOES 16 generation of spacecraft measures a wide range of electron energies, 10 energy channels from 50 keV to 4 MeV, compared to its ...

Polytropic Index and Thermodynamic Behavior of the Central Plasma Sheet Near Lunar Distances

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract In addition to making near‐Earth observations, the THEMIS/ARTEMIS mission is uniquely positioned at lunar distance, in the deep magnetotail, reaching distances of 60 RE ${R}_{E}$ and further. This vantage point allows ARTEMIS to access the plasma sheet and measure entropy evolution across convective channels, plasma flow gradients ...

Mars' O+ ${\mathbf{O}}^{+}$ and O2+ ${\mathbf{O}}_{\mathbf{2}}^{+}$ Ion Escape During Disappearing Solar Wind Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Disappearing solar wind events (DSWEs), intervals when the solar wind proton density <1 cm−3 ${\text{cm}}^{-3}$, represent one extreme of the Mars solar wind interaction. Using data from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission from February 2016 to May 2024, 154 orbits across 90 unique days were identified.
