Static spherically symmetric solutions in extended Palatini gravity. |
Abstract |
We consider static spherically symmetric configurations in a family of Palatini theories of gravity in which the lagrangian is an unspecified function of the form $f(R,R_{\mu\nu}R^{\mu\nu})$. We obtain the Tolman-Oppenheimer-Volkov equations corresponding to this class of theories and show that they recover those of $f(R)$ theories and General Relativity in the appropriate limits. We show that exact interior solutions can be found for simple matter distributions and that the exterior solution is always of Schwarzschild-de Sitter type. |
