Solar Radio Burst Fine Structures
Eduard Kontar, Daniel Clarkson, Hamish Reid +5
Solar radio bursts exhibit intricate variability in time, space, and frequency, often displaying a rich variety of fine frequency-time structures such as spikes, drift pairs, stria…
Modeling the Thermal Low-Frequency Radio Sun with Ray Tracing
Peijin Zhang, Bin Chen, Gregory Fleishman +4
Incoherent radio emission at meter--decimeter wavelengths provides a key diagnostic of the coronal thermal plasma, but at frequencies below \,1\,GHz coronal refraction can su…
Magneto-Thermal Coupling and Coronal Heating in Solar Active Regions Inferred from Microwave Observations
Alexey A. Kuznetsov, Gregory D. Fleishman, Gelu M. Nita +1
The solar corona is much hotter than the photosphere and chromosphere, but the physical mechanism responsible for heating the coronal plasma remains unidentified yet. The thermal m…
Steady-State Heating of Diffuse Coronal Plasma in a Solar Active Region
Gregory D. Fleishman, Alexey A. Kuznetsov, Gelu M. Nita
Solar corona is much hotter than lower layers of the solar atmosphere-photosphere and chromosphere. The coronal temperature is up to 1MK in quiet sun areas, while up to several MK…
Imaging Spectroscopy of Solar Radio Burst Fine Structures
E. P. Kontar, S. Yu, A. A. Kuznetsov +6
Solar radio observations provide a unique diagnostic of the outer solar atmosphere. However, the inhomogeneous turbulent corona strongly affects the propagation of the emitted radi…
