Stable Bound Orbits around Black Rings

T.Igata, H.Ishihara, Y.Takamori

We examine bound orbits of particles around singly rotating black rings. We show that there exist stable bound orbits in toroidal spiral shape near the \lq axis\rq\ of the ring, and also exist stable circular orbits on the \lq axis\rq\ as special cases. The stable bound orbits can have arbitrary large size if the thickness of the ring is less than a critical value.
