Role of magnetic shear distribution on the formation of eruptive flux ropes
Samrat Sen, Sushree S Nayak, Patrick Antolin
Erupting flux ropes play crucial role in powering a wide range of solar transients, including flares, jets, and coronal mass ejections. These events are driven by the release of st…
Dynamics of Reconnection Nanojets in Eruptive and Confined Solar Flares
Annu Bura, Arpit Kumar Shrivastav, Ritesh Patel +6
Recent observations reveal small-scale reconnection-driven plasma ejections, often termed nanojets, triggered by magnetic field interactions at slight misalignment angles. These fa…
On the Magnetic Reconnection and its Properties during a Flare Using a Magnetohydrodynamics Simulation
Sushree S Nayak, Qiang Hu, Wen He +2
We study the magnetic reconnection during a flare by investigating flare ribbon dynamics using observations and data-constrained magnetohydrodynamics (MHD) simulation. In particula…
Data-Constrained Magnetohydrodynamics Simulation of a Confined X-class Flare in NOAA Active Region 11166
Sanjay Kumar, Pawan Kumar, Sadashiv +5
In this paper, we present a magnetohydrodynamics simulation of NOAA active region 11166 to understand the origin of a confined X-class flare that peaked at 23:23 UT on 2011 March 9…
Exploring the magnetic and thermal evolution of a coronal jet
Sushree S Nayak, Samrat Sen, Arpit Kumar Shrivastav +2
Coronal jets are the captivating eruptions which are often found in the solar atmosphere, and primarily formed due to magnetic reconnection. Despite their short-lived nature and lo…
