Description
Black rings are rotating black hole solutions of 4+1-dimensional
supergravity. Recently, we have found supersymmetric black rings with
three gauge charges and regular event horizons. When lifted to ten
dimensional supergravity, the charges have interpretations as D-brane
charges, and hence it is interesting to ask for a string theoretic
interpretation of black rings. In this talk we describe first how 2-charge
black rings are related to string theory objects known as 2-charge
supertubes. We then present the 3-charge supersymmetric black rings, and
discuss three-charge supertubes.
