A study of the kinematic and volumetric co-evolution of Earth-directed CMEs
Ashutosh Pattnaik, Nat Gopalswamy, Ranadeep Sarkar +3
While flare-associated CMEs generally show a strong association between flare X-ray flux and CME kinematics, their volumetric evolution and its link to both kinematics and flare ac…
Evolution of reconnection flux during eruption of magnetic flux ropes
Samriddhi Sankar Maity, Piyali Chatterjee, Ranadeep Sarkar +1
Coronal mass ejections (CMEs) are powerful drivers of space weather, with magnetic flux ropes (MFRs) widely regarded as their primary precursors. However, the variation in reconnec…
Modelling the magnetic vectors of ICMEs at different heliocentric distances with INFROS
Ranadeep Sarkar, Nandita Srivastava, Nat Gopalswamy +1
The INterplanetary Flux ROpe Simulator (INFROS) is an observationally constrained analytical model dedicated for forecasting the strength of the southward component (Bz) of the mag…
The Automatic Identification and Tracking of Coronal Flux Ropes -- Part I: Footpoints and Fluxes
Andreas Wagner, Emilia K. J. Kilpua, Ranadeep Sarkar +5
Investigating the early-stage evolution of an erupting flux rope from the Sun is important to understand the mechanisms of how it looses its stability and its space weather impacts…
Magnetohydrodynamics evolution of three-dimensional magnetic null in NOAA active region 11515 initiated using non-force-free field extrapolation
Sanjay Kumar, Avijeet Prasad, Ranadeep Sarkar +1
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 2012 July 2. The simulat…
An Observationally Constrained Analytical Model for Predicting the Magnetic Field Vectors of ICMEs at 1 AU
Ranadeep Sarkar, Nat Gopalswamy, Nandita Srivastava
We report on an observationally constrained analytical model, the INterplanetary Flux ROpe Simulator (INFROS), for predicting the magnetic-field vectors of coronal mass ejections (…
