Study of the Kinematics and Plasma Properties of A Solar Surge Triggered due to Chromospheric Activity in AR11271
P. Kayshap, A. K. Srivastava, K. Murawski
We observe a solar surge in NOAA AR11271 using SDO AIA 304 image data on 25 August, 2011. The surge rises vertically from its origin upto a height of 65 Mm with a terminal velocity…
Numerical Simulations of Magnetoacoustic-Gravity Waves in the Solar Atmosphere
K. Murawski, A. K. Srivastava, J. A. McLaughlin +1
We investigate the excitation of magnetoacoustic-gravity waves generated from localized pulses in the gas pressure as well as in vertical component of velocity. These pulses are in…
Pulse-driven nonlinear Alfvén waves and their role in the spectral line broadening
P. Chmielewski, A. K. Srivastava, K. Murawski +1
We study the impulsively generated non-linear Alfvén waves in the solar atmosphere, and describe their most likely role in the observed non-thermal broadening of some spectral line…
Observations of Multiple Surges Associated with Magnetic Activities in AR10484 on 25 October 2003
Wahab Uddin, B. Schmieder, R. Chandra +3
We present a multiwavelength study of recurrent surges observed in Hα, UV (SOHO/EIT) and Radio (Learmonth, Australia) from the super-active region NOAA 10484 on 25 October, 2003. S…
Multiwavelength Observations of Supersonic Plasma Blob Triggered by Reconnection Generated Velocity Pulse in AR10808
A. K. Srivastava, R. Erdelyi, K. Murawski +1
Using multi-wavelength observations of Solar and Heliospheric Observatory (SoHO)/Michelson Doppler Imager (MDI), Transition Region and Coronal Explorer (TRACE) 171 Å, and H from…
