Associated scholarship(s): | 18/20689-7 - Gauss-Bonnet Stars, BE.EP.PD |

Although great efforts in the study of the composition and internal structure of compact stars have been made, the absolute ground state of matter still is an open question. The analysis of matter at high densities in the universe has as one of its fronts the characterization of gravitational waves emitted by binary systems with compact objects. The objective of this work is to characterize the polarization states of gravitational waves in f(R,T) Theory, in which the gravitational part of the action depends on a generic function of R, the Ricci scalar, and T, the trace of the energy-momentum tensor. Such a characterization, apart from contributing to the study of matter at high densities, can be corroborated by experiments like Advanced LIGO, which will soon come into operation. Furthermore, still in the scope of f(R,T) Theories, we propose to obtain the Tolman-Oppenheimer-Volkoff Equations, as well as their solutions, in such a way we can identify relevant physical quantities in the study of superdense matter in the universe.
