Solar radio emission surveillance by the Trieste Solar Radio System 2.0
2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020In this paper we describe the Trieste Solar Radio System 2.0 (TSRS 2.0), a project for a new facility dedicated to the continuous surveillance of the solar radio emission in the range 1-19 GHz. It is presently under development at the INAF Astronomical Observatory of Trieste and will be installed at the Basovizza Observing Station.

All radiation processes described can take place in the solar corona, depending on different physical characters of the radiating electrons and the coronal plasma, such as electron energy, electron pitch angle and the magnitude of the ratio f-2p/f-2H of the medium in the region where the radiators reside.

Radio evidence for solar corpuscular emission
Planetary and Space Science, 1964Abstract : This paper reviews the relation of solar radio bursts of spectral type IV to the ejection of relativistic and sub-relativistic solar particles; the relation of bursts of types II and IV to the ejection of solar plasma; and radar evidence for quiet solar streaming.

The subject of solar radio emission is quite broad and has been reviewed repeatedly in articles and books (Wild et al., 1963; Kundu, 1965; Zheleznyakov, 1970; Wild and Smerd, 1972; Rosenberg, 1976; Smerd, 1976a; Kruger, 1979; Melrose, 1980a). In addition, recent conference proceedings include issue 9 of Radiophysics and Quantum Electronics 20 (1977 ...

RADIO EMISSION FROM SOLAR FLARES
Annual Review of Astronomy and Astrophysics, 1998▪ Abstract Radio emission from solar flares offers a number of unique diagnostic tools to address long-standing questions about energy release, plasma heating, particle acceleration, and particle transport in magnetized plasmas. At millimeter and centimeter wavelengths, incoherent gyrosynchrotron emission from electrons with energies of tens of kilo ...

Pulsating Solar Radio Emission
2007A status report of current research on pulsating radio emission is given, based on working group discussions at the CESRA 2004 workshop. Quasi-periodic pulsations have been observed at all wavelength ranges of the radio band. Usually, they are associated with flare events; however since the late 90s, pulsations of the slowly-varying component of the ...

Solar and Interplanetary Radio Emissions
2010Recent progress on radio emissions from the Sun and in the interplanetary medium is reviewed, with particular emphases on type II and III solar radio bursts, and emissions from the Earth’s foreshock. Observations from single or multi spacecraft and ground-based instruments have provided new insights into interactions of beam-wave, wave-wave, and wave ...

Solar Radio Emissions and Sunspots
Nature, 1948THE ratio of the equivalent source temperatures as deduced from observations of solar electromagnetic radiation for frequencies of 80 Mc./s. and 175 Mc./s. (T80/T175) by Ryle and Vonberg1 would appear to have considerable significance to solar as well as radio physicists.

Envelope Soliton in Solar Radio Emission
Chinese Physics Letters, 2000Several envelope soliton fine structures have been observed in solar radio metric-wave emission. We present a model of longitudinal modulational instability to explain these fine structures. It is found that this instability can only occur in the condition of sound velocity being larger than Alfven velocity in corona.

Outside active regions the Sun produces radio emission that is due entirely to bremsstrahlung from thermal electrons — the quiet-Sun radio emission. Radiation of frequency f originates at and above the level where f = f p (= plasma frequency), i.e.
