New instability of non-extremal black holes: spitting out supertubes

Chowdhury, Borun D., Vercnocke, Bert

Understand

We search for stable bound states of non-extremal rotating three-charge black holes in five dimensions (Cvetic-Youm black holes) and supertubes.

  • We do this by studying the potential of supertube probes in the non-extremal black hole background and find that generically the marginally bound state of the supersymmetric limit becomes metastable and disappears with non-extremality (higher temperature).
  • However near extremality there is a range of parameters allowing for stable bound states, which have lower energy than the supertube-black hole merger.
  • Angular momentum is crucial for this effect.
