Data-constrained Magnetohydrodynamic Simulation of an Intermediate Solar Filament Eruption

The Astrophysical Journal, 2023
Abstract Solar eruptive activities could occur in weak magnetic field environments and over large spatial scales, which are especially relevant to eruptions involving intermediate or quiescent solar filaments. To handle the large scales, we implement and apply a flux rope embedding method using regularized Biot–Savart laws in the ...

A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. I. Unusual History of an Eruptive Filament

, 2013
This is the first of four companion papers, which analyze a complex eruptive event of 18 November 2003 in AR 10501 and the causes of the largest Solar Cycle 23 geomagnetic storm on 20 November 2003. Analysis of a complete data set, not considered before,

Plasma Brightenings in a Failed Solar Filament Eruption

The Astrophysical Journal, 2017
Abstract Failed filament eruptions are solar eruptions that are not associated with coronal mass ejections. In a failed filament eruption, the filament materials usually show some ascending and falling motions as well as generating bright EUV emissions.

Minifilament Eruptions as the Last Straw to Break the Equilibrium of a Giant Solar Filament

The Astrophysical Journal
Filament eruptions are magnetically driven violent explosions commonly observed on the Sun and late-type stars, sometimes leading to monster coronal mass ejections that directly affect the nearby planets’ environments.

Automated Detection of Solar Eruptions

, 2015
Observation of the solar atmosphere reveals a wide range of motions, from small scale jets and spicules to global-scale coronal mass ejections. Identifying and characterizing these motions are essential to advancing our understanding the drivers of space

Successive filament eruptions within one solar breakout event [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractThe magnetic breakout model has been widely used to explain solar eruptive activities. Here, we apply it to explain successive filament eruptions occurred in a quadrupolar magnetic source region. Based on the high temporal and spatial resolution, multi-wavelengths observations taken by the Atmospheric Imaging Assembly (AIA) on board the Solar ...

The Life Cycle of a Stratospheric Smoke Plume as Seen From EarthCARE—Tracking a Plume From Canada to Europe

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 ...

Understanding the Lateral Drifting of an Erupting Filament with a Data-constrained Magnetohydrodynamic Simulation

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).

Chain Reconnections observed in Sympathetic Eruptions

, 2016
The nature of various plausible causal links between sympathetic events is still a controversial issue. In this work, we present multi-wavelength observations of sympathetic eruptions, associated flares and coronal mass ejections (CMEs) occurring on 2013

The Microbiology and Geochemistry of the Shallow‐Water Hydrothermal Vents of the Gulf of Naples, Italy

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.
