Energy Conversion Pathways Inside Kelvin‐Helmholtz Vortices

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Energy transfer, cross‐scale coupling, and dissipation in astrophysical plasmas remain fundamental unresolved problems. The velocity‐shear–driven Kelvin–Helmholtz instability (KHI), ubiquitous in plasmas, is a key multiscale mechanism enabling plasma mixing, particle energization and the solar wind–magnetosphere coupling, making it a critical ...

Toward a Dynamic Model for Topside Ionospheric Irregularities: Spherical Harmonic Decomposition

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Ionospheric irregularities arise from highly dynamic and turbulent processes related to magnetosphere‐ionosphere coupling and can lead to electromagnetic signal distortion or loss of lock events in global navigation satellite system signals, representing a hazard associated with space weather events. For this reason, understanding and modeling

The Evolution of Photospheric Magnetic Fields at the Footpoints of Reconnected Structures in the Solar Atmosphere

The Astrophysical Journal
Magnetic reconnection is believed to play an important role in the release and conversion of energy among magnetized plasma systems. So far, we have been unable to understand under what conditions magnetic reconnection can take place.

Relative Contributions of Solar Wind Dynamic Pressure and Interplanetary Electric Field on the Early Positive Part of Main Phase of Geomagnetic Storms

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The important early declining part of the main phase (MP) of geomagnetic storms in SYM‐H (and Dst) from positive main phase onset (MPO) to 0‐level of SYM‐H was somehow missed in the treatment of the storms. We included the missed part (or revised the storms) by raising the 0‐level of SYM‐H to MPO‐level, and showed that the inclusion is ...

Energy Dissipation in Electron-only Reconnection

The Astrophysical Journal
Magnetic reconnection is a fundamental process in space and astrophysical plasmas that converts magnetic energy to particle energy. Recently, a novel kind of reconnection, called electron-only reconnection, has been observed in Earth's magnetosheath ...

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks.
