Thick shell regime in the chameleon two-body problem
Lucila Kraiselburd, Susana J. Landau, Marcelo Salgado +2
In a previous paper [Phys. Rev. D 97, 104044 (2018)] we pointed out some shortcomings of the standard approach to chameleon theories consisting in treating the small bodies used to…
Magnetic contributions in Bekenstein type models
Lucila Kraiselburd, Florencia L. Castillo, Mercedes E. Mosquera +1
In this work we analyze the spatial and time variation of the fine structure constant (α) upon the theoretical framework developed by Bekenstein [1]. We have computed the field ψre…
Constant entropy hybrid stars: a first approximation of cooling evolution
M. Mariani, M. Orsaria, H. Vucetich
We aim to study the possibility of a hadron-quark phase transition in the interior of neutron stars, taking into account different schematic evolutionary stages at finite temperatu…
Equivalence Principle in Chameleon Models
Lucila Kraiselburd, Susana J. Landau, Marcelo Salgado +2
Most theories that predict time and/or space variation of fundamental constants also predict violations of the Weak Equivalence Principle. In 2004 Khoury and Weltman proposed the s…
Scalar Resonances in Axially Symmetric Spacetimes
Ignacio F. Ranea-Sandoval, Héctor Vucetich
We study properties of resonant solutions to the scalar wave equation in several axially symmetric spacetimes. We prove that non-axial resonant modes do not exist neither in the La…
Effect of magnetic fields on equatorial circular orbits in Kerr spacetimes
Ignacio F. Ranea Sandoval, Héctor Vucetich
In this work we analyze the effects of an external magnetic field on charged particles on equatorial circular orbits in a Kerr spacetime, both in the black hole and the naked singu…
