Dorovskyy V. Solar bursts and their fine structure at the decameter radio wavelengths band

The object of the research is solar sporadic radio emission at the decameter wavelengths. The purpose of the research: the detection and analysis of the characteristics of solar radio bursts with fine structure. Methods of research: the computer data processing and computer graphics for the detection of solar radio bursts parameters. Statistical analysis. New theoretical and practical results: Type II and Type III bursts with fine structure were observed for the first time at the decameter wavelengths. Wavelike variation of the “backbone” of the Type II burst with “herringbone structure” was found. Solar S-bursts were observed and their parameters were detected firstly at the decameter wavelengths. It was found that frequency drift rates, their dependence on frequency and the distribution in frequency of the “forward” and “reverse” drift pairs were different. Physical model, which explains the specific frequency drift rates of drift pairs, was proposed. Scientific results can be used for correction ofthe existent and creation of new models of solar sporadic radio emission in the solar corona. The field of application: heliophysics and solar system physics, geophysics and solar-terrestrial relationship
