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

open access: yesJournal 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.

Photospheric Horizontal Magnetic Field Decrease Preceding a Major Solar Eruption

open access: yesThe Astrophysical Journal
Significant photospheric magnetic field changes during major solar eruptions—interpreted as coronal feedback from eruptions to the photosphere—are well-observed. However, analogous short-timescale field changes preceding eruptions are rarely reported. In

Geoeffectivity of Solar Wind Heavy Ions

open access: yesJournal 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.

Optimization of the FRi3D CME Model in EUHFORIA

open access: yesSpace 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 ...

From the Sun to the Earth: The 13 May 2005 Coronal Mass Ejection [PDF]

open access: yes, 2010
We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005. We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment ...

Coronal Mass Ejections Deflected by Newly Emerging Flux: A Combined Analytic and Numerical Study

open access: yesThe Astrophysical Journal
Newly emerging flux (NEF) has been widely studied as a trigger of solar filament eruptions, but its influence on the subsequent dynamics remains poorly explored.

Forecasting Coronal Mass Ejections Using Transformers: A Comparative Study of Flare‐Associated Versus Flare‐Independent Approaches

open access: yesSpace Weather, Volume 23, Issue 8, August 2025.
Abstract Forecasting coronal mass ejections (CMEs) remains a challenge, and no reliable, accurate forecasting method has yet been developed. Knowing that CMEs can occur in association with flares, we compare two approaches: (a) forecasting CMEs by coupling to flare forecasting, and (b) forecasting CMEs independently of flare occurrence.

Flux Cancelation: The Key to Solar Eruptions [PDF]

open access: yes, 2017
Solar coronal jets are magnetically channeled eruptions that occur in all types of solar environments (e.g. active regions, quiet-Sun regions and coronal holes).

Structure and Dynamics of Erupting Solar Prominences Using the Rolling Hough Transform: Toward a Feature-oriented Classification

open access: yesThe Astrophysical Journal
The classification of solar prominences has proven to be challenging, due to their diverse morphologies and dynamical behavior. Complexity is heightened when considering eruptive prominences, where the dynamics demand methods capable of capturing ...

Sigmoid Formation, Filament Destabilization, and Initiation of Weak Flare by Tether Cutting Reconnection

open access: yesThe Astrophysical Journal
We have studied a B-class solar flare and an associated filament eruption through multiwavelength observations. The flare is triggered at 16:24 UT on 2017 June 7 from Active Region(AR) 12661, and it maximizes at 16:54 UT.
