Rigidity and the interpretation of mass with a positive cosmological constant
Eneko Aranguren, Raül Vera
We provide an explicit counterexample to the rigidity properties underlying the interpretation of mass in the presence of a positive cosmological constant . Specifically, we con…
Improving the inference of the stellar quantities using the extended -Love-- relations
Eneko Aranguren, José A. Font, Nicolas Sanchis-Gual +1
In relativistic Astrophysics the -Love- relations refer to approximately EoS-independent relations involving the moment of inertia, Love number, and quadrupole moment through…
-Love-, and too: The role of the mass in universal relations of compact stars
Eneko Aranguren, José A. Font, Nicolas Sanchis-Gual +1
In the study of rotating neutron stars the -Love- relations refer to the existence of various approximate, equation of state-independent relations involving the moment of ine…
Review on the matching conditions for the tidal problem: towards the application to more general contexts
Eneko Aranguren, Raül Vera
The tidal problem is used to obtain the tidal deformability (or Love number) of stars. The semi-analytical study is usually treated in perturbation theory as a first order perturba…
Revisiting the -Love- relations for superfluid neutron stars
Eneko Aranguren, José A. Font, Nicolas Sanchis-Gual +1
We study the tidal problem and the resulting -Love- approximate universal relations for rotating superfluid neutron stars in the Hartle-Thorne formalism. Superfluid stars are…
A revised formalism for slowly-rotating superfluid neutron stars in general relativity
Eneko Aranguren, José A. Font, Nicolas Sanchis-Gual +1
We discuss slowly-rotating, general relativistic, superfluid neutron stars in the Hartle-Thorne formulation. The composition of the stars is described by a simple two-fluid model w…
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…
