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…

Phase-field Fracture Modelling of Thin Monolithic and Laminated Glass Plates under Quasi-static Bending

Jaroslav Schmidt, Alena Zemanová, Jan Zeman +1

A phase-field description of brittle fracture is employed in the reported four-point bending analyses of monolithic and laminated glass plates. Our aims are: (i) to compare differe…

Newmark algorithm for dynamic analysis with Maxwell chain model

Jaroslav Schmidt, Tomáš Janda, Alena Zemanová +2

This paper investigates a time-stepping procedure of the Newmark type for dynamic analyses of viscoelastic structures characterized by a generalized Maxwell model. We depart from a…

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…

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…
