Existence and uniqueness of compact rotating configurations in GR in second order perturbation theory
Marc Mars, Borja Reina, Raül Vera
Existence and uniqueness of rotating fluid bodies in equilibrium is still poorly understood in General Relativity (GR). Apart from the limiting case of infinitely thin disks, the o…
Gauge fixing and regularity of axially symmetric and axistationary second order perturbations around spherical backgrounds
Marc Mars, Borja Reina, Raül Vera
Perturbation theory in geometric theories of gravitation is a gauge theory of symmetric tensors defined on a Lorentzian manifold (the background spacetime). The gauge freedom makes…
First order perturbations of hypersurfaces of arbitrary causal character
Brien C. Nolan, Borja Reina, Kepa Sousa
In this work we study the problem of first order perturbations of a general hypersurface, i.e. with arbitrary causal character at each point. We extend the framework by Mars (Class…
Completion of the universal I-Love-Q relations in compact stars including the mass
Borja Reina, Nicolas Sanchis-Gual, Raül Vera +1
In a recent paper we applied a rigorous perturbed matching framework to show the amendment of the mass of rotating stars in Hartle's model. Here, we apply this framework to the tid…
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,…
