Die radiofrequente Strahlung der Sonnenkorona

Abstract

From the theory of the free-free-transitions of the electrons in the solar corona the absorption coefficient and optical thickness of the corona are calculated. From these the intensity of the coronal radiation at radio-frequencies is deduced for different distances from the centre of the sun's disc (Fig. 1). In fig. 2 the spectral intensity-distribution is given for radiation coming from the sun's centre (ϱ=0), from the sun's limb (ϱ=1), and from a point one solar radius outside the sun's limb.
