SOLAR FILAMENT MATERIAL OSCILLATIONS AND DRAINAGE BEFORE ERUPTION [PDF]
The Astrophysical Journal, 2014 Both large-amplitude longitudinal (LAL) oscillations and material drainage in a solar filament are associated with the flow of material along the filament axis, often followed by an eruption. However, the relationship between these two motions and a subsequent eruption event is poorly understood.

The Astrophysical Journal, 2022 Abstract Both observations and simulations suggest that the solar filament eruption is closely related to magnetic flux emergence. It is thought that the eruption is triggered by magnetic reconnection between the filament and the emerging flux. However, the details of such a reconnection are rarely presented. In this study, we report the

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Recent advances in solar physics increasingly rely on automated identification of coronal structures using machine learning. Yet most studies emphasize scientific performance without evaluating feasibility for onboard deployment to prioritize downlink observations.

Space Weather, Volume 24, Issue 6, June 2026.Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Astrophysical Journal Letters, 2022 We present two homologous quasi-periodic fast-mode propagating (QFP) wave trains excited by two small-scale filament eruptions nearby a sunspot on 2017 September 12. By using observations from several ground-based and space-based instruments, it is found

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract At the end of May 2025, extremely strong wildfires in Canada produced several pyrocumulonimbus clouds lifting the smoke particles up to the lower stratosphere. Stratospheric aerosol optical depths of more than 2.5 were observed by the ATmospheric LiDAR (ATLID) onboard of the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) satellite ...

Two Cases of Non-Radial Filament Eruption and Associated CME Deflection
UniverseThe purpose of this paper is to analyze the multi-wavelength and multi-instrument observations of two quiescent filament eruptions as well as the deflection of associated CMEs from the radial direction.

The Astrophysical Journal, 2023 Solar filaments often exhibit rotation and deflection during eruptions, which would significantly affect the geoeffectiveness of the corresponding coronal mass ejections (CMEs).

Environmental Microbiology, Volume 28, Issue 4, April 2026.This study investigated the interplay between fluid geochemistry and microbial diversity in the shallow‐water hydrothermal vents of the gulf of Naples, Italy. We found that hydrothermal fluid chemistry and the geological settings where the vents are hosted play a key role in shaping microbial distribution.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Jupiter's most intense jet at planetographic latitude 23.7°N experiences vigorous planetary‐scale disturbances. The onset consists of the outbreak of 1–3 bright clouds of convective origin developing turbulent plumes. Observed events between 1970 and 2025 shows a cycle of activity with a period in the range of 3.8–5.1 yrs interrupted between ...
