Bridging Unstratified and Stratified Simulations of the Streaming Instability for τs = 0.1 Grains

The Astrophysical Journal
The streaming instability (SI), driven by aerodynamic coupling between solids and gas under a global radial pressure gradient, concentrates solids and facilitates planetesimal formation.

Linear Stability Analysis of Relativistic Magnetized Jets: The Minimalist Approach

Universe
A minimalist approach to the linear stability problem in fluid dynamics is developed that ensures efficiency by utilizing only the essential elements required to find the eigenvalues for given boundary conditions.

Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

Effect of Transverse Magnetic Field on Kelvin–Helmholtz Instability in the Presence of a Radiation Field

The Astrophysical Journal
The dispersion relation of the magnetized Kelvin–Helmholtz (KH) instability driven by shear flow with zero thickness of the shear layer is derived theoretically based on a set of magnetohydrodynamic equations in the presence of a transverse magnetic ...

Observations and Simulation of Thermospheric Composition Changes During the 14 October 2023 Solar Eclipse

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study presents a full‐period imaging of the thermospheric composition response to the 14 October 2023 annular solar eclipse, combining GOLD (Global‐scale Observations of the Limb and Disk) far‐ultraviolet observations with solar‐irradiance‐driven WACCM‐X (Whole Atmosphere Community Climate Model with thermosphere–ionosphere extension ...

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the

Effect of Nonuniform Parallel Magnetic Field on the Kelvin–Helmholtz Instability in the Orion Nebula

The Astrophysical Journal
The surface rippled structures of Orion molecular cloud have been attributed to the Kelvin–Helmholtz (KH) instability, and the influence of magnetic field and pressure on the formation and evolution of these structures is one of the important issues that
