A Numerical Experiment on Oscillatory Magnetic Reconnection in a Laboratory Plasma System Driven by Alternating Currents
Sripan Mondal, Abhishekh Kumar Srivastava, Eric R. Priest
Using the open source MPI-AMRVAC framework, we study oscillatory reconnection in a laboratory plasma, which occurs when a magnetic null is perturbed by incoming fast magnetoacousti…
Interaction of Fast Magnetoacoustic Wave with the Localized Coronal Null and Generation of the Energetic Alfvén Wave Packet
Akash Bairagi, Abhishekh K. Srivastava, Sripan Mondal +5
In the present paper, we have performed 2.5D resistive magnetohydrodynamic simulations of the interaction of a fast magnetoacoustic wave with a localized coronal magnetic null poin…
Recurrent Coronal Jets and QPPs: Periodic Reconnection and Localized Heating Across Quiet-Sun to Active Regions
Sudheer K. Mishra, Kartika Sangal, Balveer Singh +3
We analyze quasi-periodic pulsations (QPPs) in recurrent coronal jets driven by periodic magnetic reconnection associated with successive flux emergence in the fan-spine magnetic t…
Generation of Surface Sausage Oscillations of a Current Sheet and Propagating Magnetoacoustic Waves by Impulsive Reconnection
Sripan Mondal, A. K. Srivastava, David I. Pontin +1
Magnetic reconnection and Magnetohydrodynamic (MHD) waves may well be both playing a role in coronal heating. In this paper, we simulate reconnection in the corona as a response to…
Localized Heating and Dynamics of the Solar Corona due to a Symbiosis of Waves and Reconnection
A. K. Srivastava, Sripan Mondal, Eric R. Priest +6
The Sun's outer atmosphere, the corona, is maintained at mega-Kelvin temperatures and fills the heliosphere with a supersonic outflowing wind. The dissipation of magnetic waves and…
Dynamics and Energetics of Resistive, Thermally Conductive, and Radiative Plasma in Coronal Current Sheets due to Asymmetric External Perturbation
Sripan Mondal, Akash Bairagi, A. K. Srivastava
We study the asymmetric interaction of wave-like velocity perturbation with a coronal current sheet (CS) in the presence of resistivity, thermal conduction (TC) and radiative cooli…
Characterizing Superflares in HR 1099 using Temporal and Spectral Analysis of XMM-Newton Observations
Shweta Didel, Jeewan C Pandey, A. K. Srivastava
In the present paper, we analyze three energetic X-ray flares from the active RS CVn binary HR 1099 using data obtained from XMM-Newton. The flare duration ranges from 2.8 to 4.1 h…
Generation of fast magnetoacoustic waves in the corona by impulsive bursty reconnection
Sripan Mondal, A. K. Srivastava, David I. Pontin +3
Fast-mode magnetohydrodynamic (MHD) waves in the solar corona are often known to be produced by solar flares and eruptive prominences. We here simulate the effect of the interactio…
