Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Interplanetary Type IV Solar Radio Bursts: A Comprehensive Catalog and Statistical Results

The Astrophysical Journal
Decameter hectometric (DH; 1–14 MHz) type IV radio bursts are produced by flare-accelerated electrons trapped in postflare loops or the moving magnetic structures associated with the coronal mass ejections (CMEs).

Deep Learning‐Based Prediction of High‐Speed Solar Wind Streams: Spatio‐Temporal Dependencies in Coronal Hole Dynamics

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract High‐speed solar wind streams (HSS), originating from coronal holes (CH), are key drivers of space weather disturbances and heliospheric dynamics. However, forecasting HSS remains challenging due to the evolving morphology of CH. In this study, we present a deep learning‐based framework that models the spatiotemporal relationship between CH ...

Doppler-shifted Signatures in the Chromospheric Line Profiles of II Pegasi

The Astrophysical Journal
Stellar flares are frequently accompanied by prominence eruptions, coronal mass ejections (CMEs), and other forms of plasma motion. Based on the long-term high-resolution spectroscopic monitoring data set of the RS CVn-type star II Pegasi (II Peg), we ...

Validating DIRECD: Statistical Evaluation of Coronal Mass Ejection Direction Estimates from Coronal Dimmings

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are among the most energetic phenomena in our solar system, with significant implications for space weather. Understanding their early dynamics remains challenging due to observational limitations in the low corona.

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. I. Discovery of Prominence Eruptions Associated with Superflares

The Astrophysical Journal
Young solar-type stars frequently produce superflares, serving as a unique window into the young Sun-Earth environments. Large solar flares are closely linked to coronal mass ejections (CMEs) associated with filament/prominence eruptions, but ...
