Abstract

Wormholes are fascinating alternatives to black hole geometries. In this paper, we have studied a special case of wormhole solution in the context of R=0R=0 spacetime. Our approximate analytical calculations show that under a strictly static axial gravitational perturbation of this spacetime, the magnetic-type tidal Love number (for =2\ell=2) vanishes if we keep the solution of the master equation up to linear order in the regularisation parameter of the geometry.
