On the Radio Optical Depth of the Layer Where the Temperature Equals the Brightness Temperature
Abstract
It is usually believed that the radio optical depth of the layer h* where the temperature equals the brightness temperature is independent of the frequency. This assumption is criticized from the theoretical point of view and the behaviour of τ(h*) as a function of the frequency v is computed for two different solar models.
