Query: Stable wormholes on a noncommutative-geometry background admitting a
  one-parameter group of conformal motions   When Morris and Thorne first proposed the possible existence of traversable
wormholes, they adopted the following strategy: maintain complete control over
the geometry, thereby leaving open the determination of the stress-energy
tensor. In this paper we determine this tensor by starting with a
noncommutative-geometry background and assuming that the static and spherically
symmetric spacetime admits conformal motions. This had been established in a
previous collaboration with Rahaman et al. using a slightly different approach.
Accordingly, the main purpose of this paper is to show that the wormhole
obtained can be made stable to linearized radial perturbations.
