The Sound of Clearing the Throat: Gravitational Waves from a Black Hole
  Orbiting in a Wormhole Geometry
  Current ground-based gravitational wave detectors are tuned to capture the
collision of compact objects such as stellar origin black holes and neutron
stars; over 20 such events have been published to date. Theoretically, however,
more exotic compact objects may exist, collisions of which should also generate
copious gravitational waves. In this paper, we model the inspiral of a stellar
mass black hole into a stable, non-spinning, traversable wormhole, and find a
characteristic waveform -- an anti-chirp and/or burst -- as the black hole
emerges, i.e., outspirals, into our region of the Universe. This novel waveform
signature may be useful in searches for wormholes in future gravitational wave
data or used to constrain possible wormhole geometries in our Universe.
