Exploring the generation and annihilation of three dimensional nulls through MHD simulations in initially chaotic magnetic field devoid of nulls
Yogesh Kumar Maurya, Ramit Bhattacharyya, David I. Pontin +1
Three-dimensional (3D) magnetic nulls are abundant in the solar atmosphere, as been firmly established through contemporary observations. They are established to be important magne…
Formation of an observed eruptive flux rope above the torus instability threshold through tether-cutting magnetic reconnection
Avijeet Prasad, Sanjay Kumar, Alphonse C. Sterling +4
Erupting magnetic flux ropes (MFRs) play a crucial role in producing solar flares. However, the formation of erupting MFRs in complex coronal magnetic configurations and their subs…
Magnetohydrodynamics simulation of magnetic flux rope formation in a quadrupolar magnetic field configuration
Sanjay Kumar, Avijeet Prasad, Sushree S. Nayak +2
Magnetic flux ropes (MFRs) play an important role in high-energetic events like solar flares and coronal mass ejections in the solar atmosphere. Importantly, solar observations sug…
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…
Magnetohydrodynamics evolution of three-dimensional magnetic null in NOAA active region 11515 initiated using non-force-free field extrapolation
Sanjay Kumar, Avijeet Prasad, Ranadeep Sarkar +1
Magnetohydrodynamics simulation of active region NOAA 11515 is performed to examine the initiation of the M5.6 flaring event that starts around 10:43 UT on 2012 July 2. The simulat…
Controlling degeneracy and magnetization switching in an artificial spin ice system of peanut-shaped nanomagnets
Avinash Chaurasiya, Manish Anand, Rajdeep Singh Rawat
Using extensive numerical simulations, we probe the magnetization switching in two-dimensional artificial spin ice (ASI) system consisting of peanut-shaped nanomagnets. We also inv…
