Query: Radial oscillations of a radiation-supported levitating shell in
  Eddington luminosity neutron stars   In general relativity, it has been shown that radiation-supported atmospheres
exist outside the surface of a radiating spherical body close to a radius where
the gravitational and radiative forces balance each other. We calculate the
frequency of oscillation of the incompressible radial mode of such a thin
atmospheric shell and show that in the optically thin case, this particular
mode is overdamped by radiation drag.
