General Framework for the Spontaneous Scalarization of Regular Black Holes
Ernesto Contreras, Mikaela Carrasco-Hidalgo, Pedro Bargueño +1
We investigate the spontaneous scalarization of generic, static, and spherically symmetric regular black holes supported by nonlinear electrodynamics. Starting from an arbitrary se…
Hyperbolic polytrope
M. Carrasco-H, E. Contreras, E. Fuenmayor +1
In this work, we study self-gravitating objects that obey a polytropic equation of state in hyperbolic symmetry. Specifically, we describe in detail the steps to derive the Lane-Em…
Inflation from a chaotic potential with a step
Clara Rojas, Rafael Hernández-Jiménez
In this work, we study the effects on the relevant observational parameters of an inflationary universe from a chaotic potential with a step. We numerically evolve the perturbation…
Study of scalar and tensor power spectra in the generalized Starobinsky inflationary model using semiclassical methods
Clara Rojas
In this work we solved the equation of scalar and tensor perturbations for the generalized Starobinsky inflationary model using the improved uniform approximation method and the ph…
Ultracompact stars with polynomial complexity by gravitational decoupling
M. Carrasco-Hidalgo, E. Contreras
In this work we construct an ultracompact star configuration in the framework of Gravitational Decoupling by the Minimal Geometric Deformation approach. We use the complexity facto…
Geodesic motion around hairy black holes
A. Ramos, C. Arias, R. Ávalos +1
In a recent paper (Phys. Dark Univ. {\bf 31}, 100744 (2021)) it has been obtained new static black hole solutions with primary hairs by the Gravitational Decoupling. In this work w…
