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 co…
Rotation-dependent -Love-- relations in perturbation theory
Eneko Aranguren
The so-called -Love- relations link some normalized versions of the moment of inertia, the Love number, and the quadrupole moment of a star. These relations, in principle, en…
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…
