He, Wen; Jing, Ju; Wang, Haimin; Nayak, Sushree S.; Prasad, Avijeet (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Magnetic field plays an important role in various solar eruption phenomena. The formation and evolution of the characteristic magnetic field topology in solar eruptions are critical problems that will ...

Prasad, Avijeet; Kumar, S.; Sterling, A.C.; Moore, R.L.; Aulanier, Guillaume; Bhattacharyya, R.; Hu, Q. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Context. Erupting magnetic flux ropes (MFRs) are believed to play a crucial role in producing solar flares. However, the formation of erupting MFRs in complex coronal magnetic configurations and the role of their subsequent ...

Kumar, Sanjay; Prasad, Avijeet; Sarkar, Ranadeep; Bhattacharyya, Ramit (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)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 2 July 2012. The simulation is conducted using an extrapolated ...
