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 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…
