Origin of Quasi-Periodic Pulsation at the Base of Kink Unstable Jet
Sudheer K. Mishra, Kartika Sangal, Pradeep Kayshap +3
We study a blowout jet that occurs at the west limb of the Sun on August 29, 2014 using high-resolution imaging/spectroscopic observations provided by SDO/AIA and IRIS. An i…
Observational evidence for two-component distributions describing solar magnetic bright points
G. Berrios Saavedra, D. Utz, S. Vargas Dominguez +6
Context. High-resolution observations of the solar photosphere reveal the presence of fine structures, in particular the so-called magnetic bright points (MBPs), which are small-sc…
The prominence driven forced reconnection in the solar corona and associated plasma dynamics
A. K. Srivastava, Sudheer K. Mishra, P. Jelínek
Using the multi-temperature observations from SDO/AIA on 30th December 2019, we provide a signature of prominence driven forced magnetic reconnection in the corona and associated p…
Dynamics of Sunspot Shock Waves in the Chromosphere and Transition Region
Pradeep Kayshap, Durgesh Tripathi, P. Jelinek
We study the dynamics of shock waves observed in the umbra of a sunspot using the spectroscopic observations from the Interface Region Imaging Spectrometer (IRIS). The presence of…
Propagation of Waves above a Plage as Observed by IRIS and SDO
P. Kayshap, A. K. Srivastava, S. K. Tiwari +2
Context. MHD waves are proposed to transport sufficient energy from the photosphere to heat the transition-region (TR) and corona. However, various aspects of these waves such as t…
Signatures of red-shifted footpoints in the quiescent coronal loop system
Yamini K. Rao, Abhishek K. Srivastava, Pradeep Kayshap +1
We observed quiescent coronal loops using multi-wavelength observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) on 2016 April 13. T…
Plasma flows in the cool loop systems
Yamini K. Rao, Abhishek K. Srivastava, Pradeep Kayshap +2
We study the dynamics of low-lying cool loop systems for three datasets as observed by the Interface Region Imaging Spectrograph (IRIS). Radiances, Doppler shifts and line widths a…
Pulse-beam heating of deep atmospheric layers triggering their oscillations and upwards moving shocks that can modulate the reconnection in solar flares
P. Jelínek, M. Karlický
We study processes occurring after a sudden heating of the chromosphere at the flare arcade footpoints which is assumed to be caused by particle beams. For the numerical simulation…
On the observations of rapid forced reconnection in the solar corona
A. K. Srivastava, Sudheer K. Mishra, P. Jelínek +7
Using multiwavelength imaging observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) on 03 May 2012, we present a novel physical scen…
Modelling Quasi-Periodic Pulsations in Solar and Stellar Flares
J. A. McLaughlin, V. M. Nakariakov, M. Dominique +2
Solar flare emission is detected in all EM bands and variations in flux density of solar energetic particles. Often the EM radiation generated in solar and stellar flares shows a p…
Magnetic swirls and associated fast magnetoacoustic kink waves in a solar chromospheric flux tube
K. Murawski, P. Kayshap, A. K. Srivastava +4
We perform numerical simulations of impulsively generated magnetic swirls in an isolated flux tube which is rooted in the solar photosphere. These swirls are triggered by an initia…
Oscillations excited by plasmoids formed during magnetic reconnection in vertical gravitationally stratified current-sheet
P. Jelínek, M. Karlický, T. Van Doorsselaere +1
Using the FLASH code, which solves the full set of the two-dimensional (2-D) non-ideal (resistive) time-dependent magnetohydrodynamic (MHD) equations, we study processes during the…
Spectroscopic Observations and Modelling of Impulsive Alfvén Waves Along a Polar Coronal Jet
P. Jelínek, A. K. Srivastava, K. Murawski +2
Using the Hinode/EIS 2 spectroscopic observations, we study the intensity, velocity, and FWHM variations of the strongest Fe XII 195.12 Å line along the jet to find the signatur…
Radio fiber bursts and fast magnetoacoustic wave trains
M. Karlický, H. Mészárosová, P. Jelínek
We present a model for dm-fiber bursts that is based on assuming fast sausage magnetoacoustic wave trains that propagate along a dense vertical filament or current sheet. Eight gro…
