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…

Homologous flaring activity over a sunspot light bridge in an emerging active region

Rohan E. Louis, Julia K. Thalmann

Sunspot light bridges are known to exhibit a variety of dynamic and persistent phenomena such as surges, small-scale jets etc. in the chromosphere and transition region. While it h…

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…

The formation of an atypical sunspot light bridge as a result of large-scale flux emergence

Rohan E. Louis, Christian Beck, Debi P. Choudhary

We use a combination of full-disk data from the Solar Dynamics Observatory and high-resolution data from the Dunn Solar Telescope (DST) to study the formation, structure, and evolu…

Sequential Lid Removal in a Triple-Decker Chain of CME-Producing Solar Eruptions

Navin Chandra Joshi, Alphonse C. Sterling, Ronald L. Moore +1

We investigate the onsets of three consecutive coronal mass ejection (CME) eruptions in 12 hours from a large bipolar active region (AR) observed by SDO, STEREO, RHESSI, and GOES.…

Eruptive-Impulsive Homologous M-class Flares Associated with Double-Decker Flux Rope Configuration in Mini-Sigmoid of NOAA 12673

Prabir K. Mitra, Bhuwan Joshi, Astrid M. Veronig +3

We present a multiwavelength analysis of two homologous, short lived, impulsive flares of GOES class M1.4 and M7.3, that occurred from a very localized mini-sigmoid region within t…
