A viable non-axisymmetric non-force-free field to represent solar active regions
A. Prasad, R. Bhattacharyya
A combination of analytical calculations and vectormagnetogram data are utilized to develop a non-axisymmetric non-force-free magnetic field and asses its viability in describing s…
Pre-flare coronal jet and evolutionary phases of a solar eruptive prominence associated with M1.8 flare: SDO and RHESSI observations
Bhuwan Joshi, Upendra Kushwaha, Astrid Veronig +1
We investigate triggering, activation, and ejection of a solar eruptive prominence that occurred in a multi-polar flux system of active region NOAA 11548 on 2012 August 18 by analy…
Analysis of sudden variations in photospheric magnetic fields during a large flare and their influences in the solar atmosphere
Brajesh Kumar, A. Raja Bayanna, P. Venkatakrishnan +1
The solar active region NOAA 11719 produced a large two-ribbon flare on 11 April 2013. We have investigated the sudden variations in the photospheric magnetic fields in this active…
Blowout Jets and Impulsive Eruptive Flare in a Bald-Patch Topology
R. Chandra, C. H. Mandrini, B. Schmieder +7
Context: A subclass of broad EUV and X-ray jets, called blowout jets, have become a topic of research since they could be the link between standard collimated jets and CMEs.} Aim:…
On the role of repetitive magnetic reconnections in evolution of magnetic flux-ropes in solar corona
Sanjay Kumar, R. Bhattacharyya, Bhuwan Joshi +1
Parker's magnetostatic theorem extended to astrophysical magnetofluids with large magnetic Reynolds number supports ceaseless regeneration of current sheets and hence, spontaneous…
On Understanding the Nature of Collision of Coronal Mass Ejections Observed by \textit{STEREO}
Wageesh Mishra, Yuming Wang, Nandita Srivastava
Our study attempts to understand the collision characteristics of two coronal mass ejections (CMEs) launched successively from the Sun on 2013 October 25. The estimated kinematics,…
