Query: Stellar Structure Equations in Extended Palatini Gravity   We consider static spherically symmetric stellar configurations in 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 the exterior vacuum solutions are of Schwarzschild-de Sitter type and
comment on the possible expected modifications, as compared to GR, of the
interior solutions.
