Deflection of a Filament Eruption with Three Parallel Flare Ribbons via Reconnection at an X-Point

Xiaomeng Zhang, Jinhan Guo, Yang Guo +2

On 2024 May 6, Active Region 13663 produced an X4.5-class flare associated with a filament eruption that exhibited remarkable rotation and deflection dynamics. This study aims to i…

EUV Wave and Coronal Seismology

Pooja Devi, Ramesh Chandra, Arun Kumar Awasthi +2

We present an investigation of the Extreme-Ultraviolet (EUV) wave linked to the flare that occurred on 28 October 2021, along with the associated coronal loop oscillation and type…

Counter-Streaming Velocities in a Quiescent Filament

Garima Karki, Brigitte Schmieder, Pascal Demoulin +3

Filaments/prominences are cold plasma (~ 10000 K) embedded in the solar corona, two orders of magnitude hotter. Filament plasma is structured by the magnetic field in thin elongate…

Spectroscopic investigations of a filament reconnecting with coronal loops during a two-ribbon solar flare

Reetika Joshi, Jaroslav Dudík, Brigitte Schmieder +2

In the standard 2D model of eruption, the eruption of a magnetic flux rope is associated with magnetic reconnection occurring beneath it. However, in 3D, additional reconnection ge…

Magnetic Reconnection between a Solar Jet and a Filament Channel

Garima Karki, Brigitte Schmieder, Pooja Devi +4

The solar corona is highly structured by bunches of magnetic field lines forming either loops, or twisted flux ropes representing prominences/filaments, or very dynamic structures…

Study of the excitation of large amplitude oscillations in a prominence by nearby flares

Manuel Luna, Reetika Joshi, Brigitte Schmieder +3

Large amplitude oscillations commonly occur in solar prominences, triggered by energetic phenomena such as jets and flares. On March 14-15, 2015, a filament partially erupted in tw…
