Constraining Electron‐Impact Ionization of O2 Through UV Aurora Observations at Ganymede

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract While photoionization rates of Ganymede's O2 ${\mathrm{O}}_{2}$ dominated atmosphere are well constrained, the contribution of electron‐impact ionization is rather uncertain. Previous quantitative estimates have relied on assumptions about densities and energy distributions of precipitating electrons, or on rare spacecraft measurements that ...

Effect of Field Line Torsion on the Polarization of ULF Waves

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract In this paper we suggest a simple modification of the dipole magnetic field which introduces field‐aligned currents and torsion to the field lines. The resulting field lines are not contained in the meridional planes and have resemblance to the geomagnetic field lines in the dawn and dusk flanks of the magnetosphere. We analyze polarization of

A Machine Learning Parameterization for the Internal Gravity Wave Spectrum

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract We introduce a stochastic model designed to parametrize the spectral properties of internal waves, using two functions that represent the semidiurnal spectral tidal cusps and the energy continuum between the inertial and the buoyancy frequencies.
