Figure 5: Curve aH (j) of horizon area vs. spin for five-dimensional black rings rotating along their 1 S (solid). The dashed curve corresponds to five-dimensional MP black holes (see Figure 1). The solid curve for black rings has two branches that meet at a regular, nonextremal minimally-rotating black ring at ∘ ------ j = 27∕32: an upper branch of thin black rings, and a lower branch of fat black rings. Fat black rings always have a smaller area than MP black holes. Their curves meet at the same zero-area naked singularity at j = 1.
