Theory and Interpretation of Solar Decimetric Radio Bursts
Bárta, Miroslav ; Karlický, Marian (advisor)
Theory and Interpretation of Solar Decimetric Radio Bursts (doctoral thesis) Miroslav Bárta 2002 Abstract Solar radio emission represents an important source of direct information about many physical processes related to particle acceleration in the solar atmosphere. Namely, the radio bursts - intense and highly variable component of solar radio radiation - bear many signatures of underlying physics related to primary energy release in solar flares and eruptions. Indeed, decimetric (dm) radio bursts and their careful analysis provide the closest observational insight into the region of magnetic reconnection and the particle acceleration sites. On the other hand, emission mechanisms of solar dm radio bursts are typically non-thermal, involving various plasma micro-instabilities and wave-mode transformations. High non-linearity of the radio emission process thus put strong demands on correct physical interpretation of the observed bursts and on finding the relations between observed features (e.g., intensity, frequency profile and its dynamics) and underlying physics. This doctoral thesis addresses two particular areas of research in the solar radio bursts and their utilization in the flare plasma diagnostics: (1) Physical interpretation of two particular classes of radio bursts related to solar flares, and,...
