| Abstract: | Departures from the state of LTE in the atmospheres of the secondary components of Algol-type binaries due to anisotropy of irradiation are investigated. Temperature inversion and the abnormal law of limb darkening are the most serious consequences of anisotropy of irradiation if the ratio of the effective temperatures of the components exceeds 2–2.5, providing that collisions can be neglected.Originally presented at the IAU Colloquium No. 16, held at the University of Pennsylvania, Philadelphia, Pa., U.S.A., September 8–11, 1971. |
