Junction conditions in quadratic gravity: thin shells and double layers
Borja Reina, José M. M. Senovilla, Raül Vera
The junction conditions for the most general gravitational theory with a Lagrangian containing terms quadratic in the curvature are derived. We include the cases with a possible co…
On the mass of rotating stars in Newtonian gravity and GR
Borja Reina, Raül Vera
We show how the correction to the calculation of the mass in the original relativistic model of a rotating star by Hartle [6], found recently [10], appears in the Newtonian limit,…
Hartle's model within the general theory of perturbative matchings: the change in mass
Borja Reina, Raül Vera
Hartle's model provides the most widely used analytic framework to describe isolated compact bodies rotating slowly in equilibrium up to second order in perturbations in the contex…
Revisiting Hartle's model using perturbed matching theory to second order: amending the change in mass
Borja Reina, Raül Vera
Hartle's model describes the equilibrium configuration of a rotating isolated compact body in perturbation theory up to second order in General Relativity. The interior of the body…
A local characterisation for static charged black holes
Guillermo A. González, Raül Vera
We obtain a purely local characterisation that singles out the Majumdar-Papapetrou class, the near-horizon Bertotti-Robinson geometry and the Reissner-Nordström exterior solution,…
First order perturbations of the Einstein-Straus and Oppenheimer-Snyder models
Marc Mars, Filipe C. Mena, Raül Vera
We derive the linearly perturbed matching conditions between a Schwarzschild spacetime region with stationary and axially symmetric perturbations and a FLRW spacetime with arbitrar…
