Description

In this talk, we consider the Ellis-Bronnikov wormhole to see the gravitational waves generation due to the particle motion around the wormhole. The orbiting-around and the falling-into cases are also discussed. The ringdown phase of the wormhole is also studied from the perturbation equation driven by the particle motion.
