Calculation of coronal magnetic field and density of nonthermal electrons with brightness temperature, spectral index, frequency, and turnover frequency in solar mocrowave bursts
Guangli Huang
On the basis of Dulk and Marsh\'s approximations, a self-consistent calculation of coronal magnetic field and density of nonthermal electrons with brightness temperature, spectral index, frequency, and turnover frequency in solar mocrowave bursts is proposed in this talk. Coronal magnetic field is directly or inversely proportional to brightness temperature frequency, and turnover frequency in different range of spectral index. However, Nonthermal density is always directly proportional to brightness temperature, frequency, and turnover frequency in different range of spectral index. For given spectral index, the variation of magnetic field is more sensitive to turnover frequency than that to frequency and brightness temperature.
