Dynamical and thermal evolution of localized reconnecting current sheets under varying guide-fields in the solar corona
Saksham Pande, Abhishekh Kumar Srivastava, Fabio Bacchini +9
Although magnetic reconnection in coronal current sheets (CSs) is a fundamental energy release mechanism in the solar corona, the role of guide-fields in governing its formation an…
Oblique kink waves in solar coronal streamers
Aleksandr V. Rubtsov, Valery M. Nakariakov, Dmitri Yu. Klimushkin +1
Coronal streamer kink waves excited by an impact of coronal mass ejections (CMEs) are routinely used to estimate the coronal Alfvén speed. These estimates generally assume wave pro…
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…
Effect of Solar Flares on Decayless Kink Oscillations in Nearby Coronal Loops
Zhiyi Li, Valery M. Nakariakov, Ding Yuan +1
We present a statistical study of 130 solar flares (B to X class) that lack soft X-ray quasi-periodic pulsations and show no kink oscillations of nearby coronal loops visible in SD…
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…
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…
Diagnostics of the solar coronal plasmas by magnetohydrodynamic waves: Magnetohydrodynamic seismology
Valery M. Nakariakov, Sihui Zhong, Dmitrii Y. Kolotkov +3
Macroscopic wave and oscillatory phenomena ubiquitously detected in the plasma of the corona of the Sun are interpreted in terms of magnetohydrodynamic theory. Fast and slow magnet…
2.5-D MHD Simulation of the Formation and Evolution of Plasmoids in Coronal Current Sheets
Sripan Mondal, Abhishek K Srivastava, David I. Pontin +2
In the present paper, using MPI-AMRVAC, we perform a 2.5-D numerical MHD simulation of the dynamics and associated thermodynamical evolution of an initially force-free Harris curre…
