| Abstract: | The influence of the gravitational radiation damping on the time of periastron passage of a binary system is examined. It
turns out that the gravitational radiation damping yields secular, periodic and mixed periodic variation of the time of periastron
passage. As a consequence, the crossing of the periastron occurs earlier (advance) at each revolution. A numerical estimation
of such an effect for eight binary stars is given. The results obtained are discussed. |
