The Composition and Stratospheric Fate of Aerosol Particles Originating in the Polar Vortex

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract Stratospheric aerosol plays a significant role in the Earth's energy balance, primarily through its direct interaction with solar radiation. It is also an important chemical reactor that contributes to the multiphase chemistry of ozone destruction by halogen compounds.

The Deformation of an Erupting Magnetic Flux Rope in a Confined Solar Flare

The Astrophysical Journal Letters, 2023
Magnetic flux ropes (MFRs), sets of coherently twisted magnetic field lines, are believed as core structures of various solar eruptions. Their evolution plays an important role to understand the physical mechanisms of solar eruptions, and can shed light ...

On the Relationship Between Coronal Magnetic Decay Index and CME Speed

, 2012
Numerical simulations suggest that kink and torus instabilities are two potential contributors to the initiation and prorogation of eruptive events. A magnetic parameter named decay index (i.e., the coronal magnetic gradient of the overlying fields above

Predicting Solar Filament Eruptions With Hek Filament Metadata

, 2015
Solar filaments are cool, dark channels of partially-ionized plasma that lie above the chromosphere. Their structure follows the neutral line between local regions of opposite magnetic polarity. Previous research (e.g. Schmieder et al. 2013) has shown a positive correlation (80%) between the occurrence of filament eruptions and coronal mass ejections ...

Statistical Study of Confined Filament/Prominence Eruptions during Solar Cycle 23

Proceedings of the Bulgarian Academy of Sciences, 2023
Filament/prominence eruptions can have a significant impact on Earth's upper atmosphere and space environment, and are the primary drivers of what is now called space weather. To distinguish the different types of filament eruptions we statistically examine them during the 23rd Solar cycle.

Geoeffectivity of Solar Wind Heavy Ions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract The influence of solar wind properties, such as the southward interplanetary magnetic field, on geomagnetic activity has been well established. However, the role of heavy ions (i.e., particles heavier than protons) in the solar wind on geomagnetic storms is not fully understood.

Filament Activation in Response to Magnetic Flux Emergence and Cancellation in Filament Channels

, 2015
We make a comparative analysis for two filaments that showed quite different activation in response to the flux emergence within the filament channels. The observations from the Solar Dynamics Observatory (SDO) and Global Oscillation Network Group (GONG)

Optimization of the FRi3D CME Model in EUHFORIA

Space Weather, Volume 23, Issue 9, September 2025.
Abstract To study the evolution and propagation of Coronal Mass Ejections (CMEs), the advanced magnetized flux rope CME model, Flux Rope in 3D (FRi3D), has been integrated into the European Heliospheric Forecasting Information Asset (EUHFORIA). Recent updates have been addressing the computational efficiency and numerical stability issues of this CME ...

Splitting and Eruption of an Active Region Filament Caused by Magnetic Reconnection

The Astrophysical Journal
To gain a deeper understanding of the intricate process of filament eruption, we present a case study of a filament splitting and erupting by using multiwavelength data of the Solar Dynamics Observatory. It is found that the magnetic reconnection between

On a Coronal Blowout Jet: The First Observation of a Simultaneously Produced Bubble-like CME and a Jet-like CME in a Solar Event

, 2012
The coronal blowout jet is a peculiar category among various jet phenomena, of which the sheared base arch, often carrying a small filament, experiences a miniature version of blowout eruption that produces large-scale coronal mass ejection (CME).
