Time delay of radiation from pulsar in a binary system that moves in field of Schwarzschild black hole

Abstract


A compact binary star that moves in a strong external gravitational field of a Schwarzschild black hole is considered. Decomposition of the redshift into a series with respect to the size of the binary system is obtained. This expression is used to calculate the redshift for a model binary system. Possible application of the results is discussed.

Keywords


redshift; time of arrival of pulsar pulses; supermassive black hole; general theory of relativity; reconstruction of motion
