Query: Holographic Neutron Stars   We construct in the context of the AdS/CFT correspondence degenerate
composite operators in the conformal field theory that are holographically dual
to degenerate stars in anti de Sitter space. We calculate the effect of the
gravitational back-reaction using the Tolman-Oppenheimer-Volkoff equations, and
determine the "Chandrasekhar limit" beyond which the star undergoes
gravitational collapse towards a black hole.
