Space Weather, Volume 24, Issue 6, June 2026.Abstract This study develops a semi‐empirical framework for Dst index forecasting by integrating the PPMLR‐MHD model of Earth's magnetosphere with four established empirical models (Burton, UCB, AK2, and Wang). The framework partitions the physics: global magnetopause and tail currents are simulated by MHD, while the ring current contribution is ...

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading
Space Weather, Volume 24, Issue 6, June 2026.Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Prediction Efficiency Skill Scores for Event Detection Analysis
Space Weather, Volume 24, Issue 6, June 2026.Abstract Prediction efficiency (PE) is a skill score that compares the data‐model metric of mean square error against the variance of the observations (i.e., using the average of the observed values as the “reference model” in the general skill score formula).

The Astrophysical JournalThe dispersion measures (DMs) of fast radio bursts (FRBs) can be used as powerful probes of the distribution of extragalactic plasma. With a large enough sample, the free-electron–galaxy power spectrum P _eg can be measured by cross-correlating FRB DMs ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The substorm current wedge constitutes the backbone of the substorm current system. Its field‐aligned current components include an upward current in the premidnight sector and a downward current in the midnight‐morning sector, which connect the auroral ionosphere to the magnetotail.

Dynamo cycles in global convection simulations of solar-like stars
, 2018 Context. Several solar-like stars exhibit cyclic magnetic activity similar to the Sun as found in photospheric and chromospheric emission. Aims. We seek to understand the physical mechanism involved in rotational dependence of these activity cycle ...

Global Simulations of Self-gravitating Magnetized Protoplanetary Disks
, 2020 In the early stages of a protoplanetary disk, turbulence generated by gravitational instability (GI) should feature significantly in the disk’s evolution. At the same time, the disk may be sufficiently ionized for magnetic fields to play some role in the

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The Kelvin‐Helmholtz instability (KHI) mediates the viscous‐like solar‐terrestrial interaction by generating magnetopause surface waves that quickly become non‐linear. Basic theory predicts the locally most‐unstable linear wave dominates.
