Charged rotating wormholes: charge without charge

Autor: Kim, Hyeong-Chan, Kim, Sung-Won, Lee, Bum-Hoon, Lee, Wonwoo

We present a family of charged rotating wormhole solutions to the Einstein-Maxwell equations, supported by anisotropic matter fields. We first revisit the charged static cases and analyze the conditions for the solution to represent a wormhole geomet

Wormhole Effective Mass and Gravitational Waves by Binary Systems Containing Wormhole

Autor: Kim, Sung-Won

We considered the generation of gravitational waves by the binary system associated with a wormhole. In the Newtonian limit, the gravitational potential of a wormhole requires the effective mass of the wormhole taking into account radial tension effe

Gravitational Waves by Perturbation of a Slowly Rotating Thin-Shell Wormhole

Autor: Kim, Sung-Won

Publikováno v: Journal of the Korean Physical Society (2023)

In this paper, the gravitational wave generation by a slowly rotating thin-shell wormhole is considered. Since the rotating thin-shell wormhole is assumed to be an axisymmetric rigid body, the rotation axis coincides with the largest principal axis w

Gravitational Waves by the Perturbation of a Rotating Axisymmetric Rigid Body

Autor: Kim, Sung-Won

Precession is one of the important mechanisms of gravitational wave generation in astrophysics. In general, free precession of a rigid body can be caused by the rotation of a triaxial body. In the case of symmetric body, if only the principal axis do
