Radio-Frequency Radiation from the Quiet Sun
Australian Journal of Scientific Research Series A: Physical Sciences, 1950The equation of transfer of radiation is used in a ray treatment of radio-frequency radiation from the solar atmosphere in the absence of solar activity. The chromosphere and the corona are represented as regions of uniform temperature. However, a range of temperatures is considered in order to allow for uncertainties in the temperature distribution in

A Note on the Long-Period Variation in the Radio-Frequency Radiation from the Quiet Sun
Publications of the Astronomical Society of Japan, 1953Abstract The apparent temperature of the quiet sun measured at radio frequencies is calculated with varying value of the electron density in the corona and chromosphere to see how it changes according to a sunspot cycle. The electron temperature in the chromosphere is assumed to increase exponentially with height until it reaches a ...

Temperature Radiation from the Quiet Sun in the Radio Spectrum
Nature, 1946The radio-frequency emissivity of the sun considered as a black body is proportional toTλ-2 per unit frequency increment, where T is the temperature of the radiating region, and λ is the wave-length of the radiation. The sensitivity of radio equipment is now such that it is possible to detect this radiation on the shorter wave-lengths in the radio ...
