Anomalous limb darkening in the atmospheres of components of close binary systems with a strong reflection effect

It is shown that in close binary systems of the Algol type, the companions of which are of spectral type K0- K2 and later, there is a temperature inversion in the surface layers of the photosphere and, as a consequence, the angular distribution of the intensity of escaping radiation for individual small areas proves to differ considerably from the limb- darkening law in the spherically symmetrical case.
