Depolarization of radio bursts due to reflection off sharp boundaries in the solar corona
It is argued that depolarization of solar radio bursts requires reflection off boundary layers no thicker than about a wavelength (a few meters at most) between regions with large density ratios. The implied inhomogeneities suggest that the corona is much more highly and sharply structured than can be resolved from observations at other wavelengths. A simplified version of magnetoionic theory i...
متن کاملSolar Radio Bursts and Space Weather
Space Weather is the study of the conditions in the solar wind that can affect life on the surface of the Earth, particularly the increasingly technologically sophisticated devices that are part of modern life. Solar radio observations are relevant to such phenomena because they generally originate as events in the solar atmosphere, including flares, coronal mass ejections and shocks, that prod...
متن کاملDetermination of fractal dimensions of solar radio bursts
We present a dimension analysis of a set of solar type I storms and type IV events with different kind of fine structures, recorded at the Trieste Astronomical Observatory. The signature of such types of solar radio events is highly structured in time. However, periodicities are rather seldom, and linear mode theory can provide only limited interpretation of the data. Therefore, we performed an...
متن کاملEffects of Solar Radio Bursts on Wireless Systems
We review the state of current understanding of the potential for interference and interruption of service of wireless communications systems due to solar radio bursts. There have been several reported instances of an enhanced rate of dropped cell-phone calls during solar bursts, and the design of current base station systems make them vulnerable to problems near sunrise and sunset for antennas...
متن کاملOF THE WORKSHOP : MECHANISMS FOR SOLAR TYPE lII RADIO BURSTS
In situ satellite observations of type III burst exciters at 1 AU show that the beam does not evolve into a plateau in velocity space, contrary to the prediction quasilinear theory. The observations can be explained by a theory that includes mode coupling effects due to excitation of the parametric oscillating two-stream instability and its saturation by anomalous resistivity. The time evolutio...
