The role of gyro-resonance radiation in the slowly varying component of the solar radio emission

In this paper we investigate the contribution of gyro-resonance to the SVC of the solar radio emission. We calculated the spatial distributions of the gyroresonance radiation over uinpolar and bipolar active regions at a number of wavelengths and we found some interesting features. We also calculated the spectra of flux and polarization and our results were in general agreement with observations. This suggests that the gyro-resonance radiation is indeed an Important mechanism for the solar SVC.
