Kinetic Processes to Radio Burst: First Observational-driven Study in Coronal Loops
Mehdi Yousefzadeh, Marian Karlicky, Artem Koval +3
Understanding the origin of coherent solar radio bursts requires linking macroscopic coronal structures with the kinetic processes responsible for wave generation. We investigate e…
Radio, X-ray, and EUV signatures of internal and external reconnection of an erupting flux rope
Jana Kašparová, Jaroslav Dudík, Marian Karlický +5
We analyse imaging (EUV, X-ray) and spectral (radio, X-ray) data obtained by ground based and space instruments on board space missions both on Earth (Fermi, Hinode, Solar Dynamics…
Slowly positively drifting bursts generated by large-scale magnetic reconnection
Alena Zemanová, Marian Karlický, Jana Kašparová +2
The slowly positively drifting bursts (SPDBs) are rarely observed in radio emission of solar flares. To understand how the SPDBs are generated, we studied the radio observations at…
KAPPA: A Package for Synthesis of Optically Thin Spectra for the Non-Maxwellian Kappa-Distributions. III. Improvements to Ionization Equilibrium and Extension to Kappa < 2
Elena Dzifcakova, Jaroslav Dudik, Martina Pavelkova +2
The KAPPA package is designed for calculations of optically thin spectra for the non-Maxwellian \k{appa}-distributions. This paper presents extension of the database to allow calcu…
Filament Leg--Leg Reconnection as a Source of Prominent Supra-Arcade Downflows
Jaroslav Dudik, Guillaume Aulanier, Jana Kasparova +4
We report on interaction of the legs of the erupting filament of 2012 August 31 and associated prominent supra-arcade downflows (P-SADs) as observed by the Atmospheric Imaging Asse…
Observation of all pre- and post-reconnection structures involved in three-dimensional reconnection geometries in solar eruptions
Jaroslav Dudik, Juraj Lorincik, Guillaume Aulanier +2
We report on observations of the two newly-identified reconnection geometries involving erupting flux ropes. In 3D, a flux rope can reconnect either with a surrounding coronal arca…
Observations of a Footpoint Drift of an Erupting Flux Rope
Alena Zemanova, Jaroslav Dudik, Guillaume Aulanier +2
We analyze the imaging observations of an M-class eruptive flare of 2015 November, 4. The pre-eruptive H alpha filament was modelled by the non-linear force free field model, which…
Solar radio burst associated with the falling bright EUV blob
Marian Karlicky, Alena Zemanova, Jaroslav Dudik +1
At the beginning of the 4 November 2015 flare, in the 1300 -- 2000 MHz frequency range, we observed a very rare slowly positively drifting burst. We searched for associated phenome…
Spectroscopic diagnostics of the non-Maxwellian -distributions using SDO/EVE observations of the 2012 March 7 X-class flare
Elena Dzifcakova, Alena Zemanova, Jaroslav Dudik +1
Spectroscopic observations made by the Extreme Ultraviolet Variability Experiment (EVE) on board the Solar Dynamics Observatory (SDO) during the 2012 March 7 X5.4-class flare (SOL2…
Imaging and Spectroscopic Observations of a Transient Coronal Loop: Evidence for the Non-Maxwellian -Distributions
Jaroslav Dudik, Simon Mackovjak, Elena Dzifcakova +8
We report on the SDO/AIA and Hinode/EIS observations of a transient coronal loop. The loop brightens up in the same location after the disappearance of an arcade formed during a B8…
