Query: Properties of non-extremal enhancons   We study the supergravity solutions describing non-extremal enhancons. There
are two branches of solutions: a `shell branch' connected to the extremal
solution, and a `horizon branch' which connects to the Schwarzschild black hole
at large mass. We show that the shell branch solutions violate the weak energy
condition, and are hence unphysical. We investigate linearized perturbations of
the horizon branch and the extremal solution numerically, completing an
investigation initiated in a previous paper. We show that these solutions are
stable against the perturbations we consider. This provides further evidence
that these latter supergravity solutions are capturing some of the true physics
of the enhancon.
