Abstract : | Coronal Mass Ejections(CMEs) being one of the main drivers for space
weather, it becomes essential to understand their initiation and evolution in
the solar corona. It is also crucial to perform numerical simulations to probe
the dynamics of CMEs in the inner corona for a better understand the CME
initiation and evolution in this region. We have performed the numerical simu-
lations of CMEs in the Magnetohydrodynamics framework using MPI-AMRVAC
in 2.5D. For the initiation, we have adopted the breakout model in which we
have three magnetic arcades with alternative polarities embedded in a dipole
magnetic field. In this multipolar topology, when we impose the shear stress
at the solar base of one of the arcades, this sheared arcade reconnects with
the neighbouring arcade and gives rise to the CME. We perform the forward
modelling on this simulated data in Fe XIV and Fe XI emission lines visible
in Visible Emission Line Coronagraph (VELC) on-board Aditya-L1 and estimate how
line intensity, Doppler velocities, and line widths vary. The VELC will also be
looking at the inner corona, so the comparison between the observation and the
simulated data will help us to understand the kinematics of the CMEs. |
