Elongation of a Solar Filament and its Three-Dimensional Numerical Reconstruction for Magnetic Structures
Garima Karki, Jinhan Guo, Brigitte Schmieder +4
Quiescent filaments are prominent features of the solar atmosphere, and their evolution reflects the coronal magnetic field's response to photospheric magnetic activity. Here, we r…
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…
Observational Characteristics of solar EUV waves
Ramesh Chandra, Pooja Devi, P. F. Chen +4
Extreme-ultraviolet (EUV) waves are one of the large-scale phenomena on the Sun. They are defined as large propagating fronts in the low corona with speeds ranging from a few tens…
Solar Jet on 2014 April 16 Modeled by Kelvin--Helmholtz Instability
M. Bogdanova, I. Zhelyazkov, R. Joshi +1
We study here the arising of Kelvin--Helmholtz Instability (KHI) in one fast jet of 2014 April 16 observed by the Atmospheric Imaging Assembly (AIA) on board Solar Dynamics Observa…
Large-Amplitude Longitudinal Oscillations Triggered by the Merging of Two Solar Filaments: Observations and Magnetic Field Analysis
M. Luna, Y. Su, B. Schmieder +2
We follow the eruption of two related intermediate filaments observed in H (from GONG) and in EUV (from SDO/AIA) and the resulting large-amplitude longitudinal oscillations of t…
A Study of a long duration B9 flare-CME event and associated piston-driven shock
R. Chandra, P. F. Chen, A. Fulara +2
We present and discuss here the observations of a small long duration GOES B- class flare associated with a quiescent filament eruption, a global EUV wave and a CME on 2011 May 11.…
Slippage of Jets Explained by the Magnetic Topology of NOAA Active Region 12035
R. Joshi, B. Schmieder, R. Chandra +3
In this study, we present the investigation of eleven recurring solar jets originated from two different sites (site 1 and site 2) close to each other (~ 11 Mm) in the NOAA active…
Two Step Filament Eruption During 14-15 March 2015
R. Chandra, B. Filippov, R. Joshi +1
We present here an interesting two-step filament eruption during 14-15 March 2015. The filament was located in NOAA AR 12297 and associated with a halo Coronal Mass Ejection (CME).…
The transition from eruptive to confined flares in the same active region
F. P. Zuccarello, R. Chandra, B. Schmieder +2
Solar flares are sudden and violent releases of magnetic energy in the solar atmosphere that can be divided in eruptive flares, when plasma is ejected from the solar atmosphere, re…
Blowout Jets and Impulsive Eruptive Flare in a Bald-Patch Topology
R. Chandra, C. H. Mandrini, B. Schmieder +7
Context: A subclass of broad EUV and X-ray jets, called blowout jets, have become a topic of research since they could be the link between standard collimated jets and CMEs.} Aim:…
Multi-wavelength view of an M2.2 Solar Flare on 26 November 2000
R. Chandra, V. K. Verma, S. Rani +1
In this paper, we present a study of an M2.2 class solar flare of 26 November 2000 from NOAA AR 9236. The flare was well observed by various ground based observatories (ARIES, Lear…
Can a Fast-mode EUV Wave Generate a Stationary Front?
P. F. Chen, C. Fang, R. Chandra +1
The discovery of stationary "EIT waves" about 16 years ago posed a big challenge to the then favorite fast-mode wave model for coronal "EIT waves". It encouraged the proposing of v…
Kelvin--Helmholtz instability in an active region jet observed with Hinode
I. Zhelyazkov, R. Chandra, A. K. Srivastava
Over past ten years a variety of jet-like phenomena were detected in the solar atmosphere, including plasma ejections over a range of coronal temperatures being observed as extreme…
Kelvin--Helmholtz instability of magnetohydrodynamic waves propagating on solar surges
