Long-Periodic Transverse Oscillations of Coronal Loops and Modulations of Solar Microwave Radiation ()
S. 435 - 444doi:10.1553/PRE7s435 Verlag der Österreichischen Akademie der Wissenschaften
Abstract: The paper deals with interpretation of long-periodic (minutes, e.g. < 0.01 Hz) modulations, detected in the microwave records during flaring events on the Sun, as the signatures of large scale transverse oscillations of coronal loops, observed at the same time by TRACE. In the case of transverse large scale oscillatory motions of a loop a properly located observer, besides of the modulation caused by motion of the emission diagram pattern at the main oscillation frequency, may see also a modulation at double frequency of the loop oscillation, resulted by a varying magnetic field during each inclination of the loop, as well as weaker higher harmonics. Identification of such ”modulation pairs” in the dynamic spectra of solar microwave emission and their association with the observed oscillating coronal loops form the major result of the undertaken investigation. Three different events with the detected by TRACE post-flare oscillating loops were considered in that study (Mar.23,2000; Sep.15,2001; Sep.07,2001).

… The 7th International Workshop on "Planetary, Solar and Heliospheric Radio Emissions" is the continuation of an established tradition: This PRE VII conference followed previous successful international workshops held at Graz, Austria, in 1984, 1987, 1991, 1996, 2001, and 2005. This 7th workshop in September 2010 offered again the unique opportunity to discuss the observations from Cassini at Saturn and to investigate the measurements by other spacecraft and from the ground of the Jovian, terrestrial and solar radio emissions, also including studies on radiation from exoplanetary sources.
