Onset and evolution of solar flares: Application of 2D and 3D models of magnetic reconnection
Bhuwan Joshi, Prabir K. Mitra, Astrid M. Veronig +1
The contemporary multi-wavelength observations have revealed various important features during solar flares which, on one hand, support the two-dimensional (2D) "standard flare mod…
Homologous compact major blowout-eruption solar flares and their production of broad CMEs
Suraj Sahu, Bhuwan Joshi, Alphonse C. Sterling +2
We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series of solar blowout-eruption flares with successively increasing int…
A Transient Coronal Sigmoid in Active Region NOAA 11909: Build-up Phase, M-class Eruptive Flare, and Associated Fast Coronal Mass Ejection
Hema Kharayat, Bhuwan Joshi, Prabir K. Mitra +2
In this article, we investigate the formation and disruption of a coronal sigmoid from the active region (AR) NOAA 11909 on 07 December 2013, by analyzing multi-wavelength and mult…
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…
Evolutionary stages and triggering process of a complex eruptive flare with circular and parallel ribbons
Navin Chandra Joshi, Bhuwan Joshi, Prabir K. Mitra
We report multi-wavelength study of a complex M-class solar eruptive flare that consists of three different sets of flare ribbons, viz. circular, parallel, and remote ribbons. Magn…
Successive occurrences of quasi-circular ribbon flares in a fan-spine-like configuration involving hyperbolic flux tube
Prabir K. Mitra, Bhuwan Joshi
We present a comprehensive analysis of the formation and evolution of a fan-spine-like configuration that developed over a complex photospheric configuration where dispersed negati…
