Dynamics of filaments, flares and coronal mass ejections (CMEs)
… activity, and the properties of the associated magnetic field for the development of forecasts of solar activity and space weather. Both statistical and case studies have been carried out. The topics covered in this dissertation are: the statistical relationship among phenomena of solar …

Radio-derived three-dimensional structure of a solar active region
… of the most violent events observed on the Sun, some of which have a direct impact to modern civilization. Efforts to understand and predict such events require determination of the three-dimensional distributions of density, temperature, and magnetic fields above such active regions. This …

High resolution spectropolarimetric diagnostics of weak, small-scale magnetic fields in the solar photosphere
… there exists a substantial amount of ‘hidden’ magnetic energy in the quiet solar photosphere, and unlocking an understanding of this phenomenon requires the study of magnetic activity on the smallest scales accessible to observations. With the advent of next generation high resolution …

Relationship between photospheric magnetic fields and coronal activities
… known to be related to the evolution of surface magnetic fields. This dissertation studies the evolution of photospheric magnetic fields and flow fields and their relation to the properties of these two coronal emission components. The key issue in the study of the steady coronal emission is the …
