Hall effect on the magnetic reconnections during the evolution of a three-dimensional magnetic flux rope
Kamlesh Bora, Satyam Agarwal, Sanjay Kumar +1
We present a novel Hall magnetohydrodynamics (HMHD) numerical simulation of a three-dimensional (3D) magnetic flux rope (MFR) -- generated by magnetic reconnections from an initial…
Magnetic reconnections in the presence of three-dimensional magnetic nulls and quasi-separatrix layers
Sanjay Kumar, Sushree S. Nayak, Avijeet Prasad +1
Three-dimensional (3D) magnetohydrodynamic simulations are carried out to explore magnetic reconnections in the presence of 3D magnetic nulls and quasi-separatrix layers (QSLs). Th…
Magnetohydrodynamic Simulation of Magnetic Null-point Reconnections and Coronal dimmings during the X2.1 flare in NOAA AR 11283
Avijeet Prasad, Karin Dissauer, Qiang Hu +4
The magnetohydrodynamics of active region NOAA 11283 is simulated using an initial non-force-free magnetic field extrapolated from its photospheric vector magnetogram. We focus on…
Determination of Power of Groove fields under Dirichlet conditions associated with axisymmetric Electromagnetic fields
Sanjay Kumar, Rakhi Tiwari
The present paper gives an interaction of electromagnetic waves with a smooth convex tri-angular obstacle and its adjacent wedge regions. We attempt to find the power of groove fie…
Determination of Power of Groove fields belonging to the wedge regions adjacent to a convex triangular obstacle associated with Dirichlet conditions subject to axially independent EM fields
Sanjay Kumar, Suresh K. Shukla
A convex triangular obstacle forms a vital part of a periodic echellete grating. A triangular grating is characterized by three parameters like period, depth and flare angle. Knowl…
Magnetohydrodynamic simulation of magnetic null-point reconnections in NOAA AR12192 initiated with an extrapolated non-force-free-field
A. Prasad, R. Bhattacharyya, Qiang Hu +2
Magnetohydrodynamics of the solar corona is simulated numerically. The simulation is initialized with an extrapolated non-force-free magnetic field using the vector magnetogram of…
