Research Projects

solar coronal transients are the intermittent release of energy in the solar atmosphere, causing large-scale events like solar flares and coronal mass ejections (CMEs) to disrupt satnav. Understanding the physics of these transients is crucial for predicting their potential space-weather influences. The project aims to obtain a detailed understanding of the source regions dynamics of these transients, which will help us realize their potential space-weather influences. Magnetic energy stored in the outermost atmospheric layer of the sun is believed to be crucial for the transients. However, a detailed understanding of the process is still lacking. Magnetic reconnection, a localized diffusive process that generates heat and mass flow by changing magnetic topology, is responsible for energy release. The project proposes using data assimilated numerical simulations and multi-wavelength observations to diagnose the physics of reconnections and the origin of the transients. To identify potential locations for host reconnections, the magnetic topology of the source regions is of paramount importance. The project will generate the source region coronal magnetic field by extrapolating the photospheric magnetic field using a novel extrapolation technique. The project will also examine the role of reconnections in the formation of magnetic structures such as flux ropes, which are crucial in generating large-scale transients. The project will analyze and compare multi-wavelength data from space-borne missions and ground-based observations with the simulation results.
