| dc.description | In this work we are revisiting the well studied Ellis wormhole solution in a Horndeski theory motivated from the Kaluza-Klein compactification procedure of the more fundamental higher dimensional Lovelock gravity. We show that the Ellis wormhole is analytically
supported by a gravitational theory with a non-trivial coupling to the Gauss-Bonnet term
and we expand upon this notion by introducing higher derivative contributions of the scalar
field. The extension of the gravitational theory does not yield any back-reacting component
on the spacetime metric, which establishes the Ellis wormhole as a stealth solution in the
generalized framework. We propose two simple mechanisms that dress the wormhole with
an effective ADM mass. The first procedure is related to a conformal transformation of the
metric which maps the theory to another Horndeski subclass, while the second one is inspired
by the spontaneous scalarization effect on black holes. | |
