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 DudÃk, 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…
High-resolution observational analysis of flare ribbon fine structures
Jonas Thoen Faber, Reetika Joshi, Luc Rouppe van der Voort +4
Context. Since the mechanism of energy release from solar flares is still not fully understood, the study of fine-scale features developing during flares becomes important for prog…
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…
