Stellar models with like--Tolman IV complexity factor
J. Andrade, E. Contreras
In this work, we construct stellar models ba-\break sed on the complexity factor as a supplementary condition which allows to close the system of differential equations arising fro…
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…
Gravitational Cracking of General Relativistic Polytropes: a generalized scheme
P. León, E. Fuenmayor, E. Contreras
We discuss the effect that small fluctuations of both local anisotropy and energy density, may have on the occurrence of cracking in spherical compact objects satisfying a polytrop…
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…
Gravitational cracking and complexity in the framework of gravitational decoupling
E. Contreras, E. Fuenmayor
In this work we analyse the stability of self gravitating spheres in the context of gravitational cracking. Besides exploring the role played by the anisotropy in the occurrence of…
Thermodynamics of scale-dependent Friedmann equations
Pedro Bargueno, Ernesto Contreras, Angel Rincon
In this work, the role of a time-varying Newton constant under the scale-dependent approach is investigated in the thermodynamics of the Friedman equations. In particular, we show…
