Compact objects in modified gravity: junction conditions and other viability criteria

| Sumario: | The purpose of this Thesis is to improve our understanding of the strong-field regime of gravitational interactions, where deviations from the theory of General Relativity (GR) are expected to be found on theoretical grounds. In particular, our investigations have been concerned with the formulation and application of junction conditions (which govern stellar collapse, black-hole formation and the dynamics of more exotic compact objects), as well as with other viability criteria necessary for modified gravity theories and their solutions to be physically admissible (such as stability or the avoidance of singularities). We will concentrate on two paradigmatic modifications of GR, namely, f (R) theories (specially on the metric formulation) and the ghost-free sub-class of Poincaré Gauge Gravity... |
