Relativistic rings due to Schwarzschild gravitational lensing

Abstract

Strong gravitational lensing in the Schwarzschild metric is considered in the case when the source, a point lens, and the observer are situated on a straight line. Angular sizes and magnification factors are calculated for relativistic rings formed by the photons which undergo one or several turns around the black hole.
