Abstract
In the original language
We present1 a generalization of the Rezzolla-Zhidenko theory-agnostic parametrization of black-hole spacetimes to accommodate spherically-symmetric Lorentzian, traversable wormholes (WHs) in an arbitrary metric theory of gravity. By applying our parametrization to various known WH metrics and performing calculations involving shadows and quasinormal modes, we show that only a few parameters are important for finding potentially observable quantities in a WH spacetime.
