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…
Two-stage evolution of an extended C-class eruptive flaring activity from sigmoid active region NOAA 12734: SDO and Udaipur-CALLISTO observations
Bhuwan Joshi, Prabir K. Mitra, R. Bhattacharyya +4
We present a multi-wavelength investigation of a C-class flaring activity that occurred in the active region NOAA 12734 on 8 March 2019. The investigation utilises data from AIA an…
Evolution of three-dimensional coherent structures in Hall magnetohydrodynamics
Kamlesh Bora, Ramit Bhattacharyya, Piotr K. Smolarkiewicz
The work extends the computational model EULAG-MHD to include Hall magnetohydrodynamics (HMHD)---important to explore physical systems undergoing fast magnetic reconnection at the…
Successive flux rope eruptions from -Sunspots region of NOAA 12673 and associated X-class eruptive flares on 2017 September 6
Prabir K. Mitra, Bhuwan Joshi, Avijeet Prasad +2
In this paper, we present a multi-wavelength analysis of two X-class solar eruptive flares of classes X2.2 and X9.3 that occurred in the sigmoidal active region NOAA 12673 on 2017…
Study of magnetic field topology of active region 12192 using an extrapolated non-force-free magnetic field
A. Prasad, R. Bhattacharyya, Q. Hu +2
The solar active region (AR) 12192 was one of the most flare productive region of solar cycle 24, which produced many X-class flares; the most energetic being an X3.1 flare on Octo…
Simulated evolution of three-dimensional magnetic nulls leading to generation of cylindrically-shaped current sheets
Sanjay Kumar, R. Bhattacharyya
The performed magnetohydrodynamic simulation examines the importance of magnetofluid evolution which naturally leads to current sheets in the presence of three-dimensional (3D) mag…
