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…
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…
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…
The collisions of high-velocity clouds with the galactic halo
Petr Jelinek, Gerhard Hensler
Spiral galaxies are surrounded by a widely distributed hot coronal gas and seem to be fed by infalling clouds of neutral hydrogen gas with low metallicity and high velocities. We n…
