Perihelion precession and deflection of light in gravitational field of wormholes

摘要

Quite exotic relativistic objects known as wormholes are hypotheticalcandidates for central machine of active galactic nuclei as well as blackholes. We find the magnitude of the perihelion precession and the deflection oflight in gravitational field of a wormhole and compare them with those for ablack hole. The impact parameter is taken to be much larger than the wormholethroat size. We show that the relative difference between results for a blackhole and a wormhole may be significant and amount to tens of percent.
