Abstract

Some of the effects extreme gravity would have on the propagation of particles inside and around constant density ultracompact stars are examined. The possible observational characteristics due to the gravitational lensing of surface hot spots are examined. The change that would be seen in the Eddington luminosity near such an object is computed. It is shown that such stars would exhibit a 'neutrino' sphere inside the surface and a 'neutrino cloud' partially exterior to the surface.
