Due to the presence of magnetic fi eld, the solar atmosphere is highly structured and manifests a myriad of transients of di fferent spatial and temporal scales. From spicules to coronal mass ejections (CMEs), transition region jets to sunspots; transients of different spatial and temporal scales are found in the solar atmosphere. In spite of decades of observations, our understanding of the solar transients is still poor. Some of the long debated issues are the nature and sources of propagating disturbances (PDs) in the solar corona, drivers of transverse and longitudinal oscillations in the coronal loops, monitoring CMEs in the heliosphere and estimating their arrival times on the Earth etc. In my PhD thesis, I attempted to study the properties of a few small and large-scale transients combining multi-wavelength observations using space-based instruments hoping to address some of the long-standing problems. The fi rst part of the thesis is focussed on the study of the dynamics of the small-scale coronal transients in the solar atmosphere and their interaction with other magnetic structures. The second part of the thesis is focussed on the study of the large-scale coronal transients such as CMEs which are the eruptions of magnetic field and plasma from the atmosphere of the Sun into the heliosphere. In this talk, I will outline some of the major results of my research work done during my PhD tenure. |
