RADIO-EMISSION FROM CORONAL STREAMERS

Different models of coronal streamers are used to calculate the radio brightness temperature at the wavelengths of observation of the Nancay s Radioheliograph. Calculation are performed assuming the location of the streamer both on the disk and at the limb. Their comparison with o bservations show that a satisfactory agreement with a particular model can be found in the shape and in the relative enhancement of the stre amer with respect to the quiet Sun, although the absolute values of th e computed brightness temperatures are much higher than the observed o nes.
