Query: Stability of linear dilaton black holes at the Hagedorn temperature   We study the thermodynamics and the small fluctuations of a linear dilaton
black hole, in an S-dual version of the near-horizon limit of type IIB NS5
branes. The thermodynamical analysis shows that the black hole is in a Hagedorn
phase, with marginal stability. The dynamical analysis confirms that the speed
of sound of the dual theory vanishes and that there are no evident
instabilities at the level of supergravity. We clarify the physical meaning of
some singularities of the retarded correlator that were thought to lead to
instabilities.
