Scalar QNMs for higher dimensional black holes surrounded by quintessence in Rastall gravity
J. P. Morais Graça, Iarley P. Lobo
The spacetime solution for a black hole, surrounded by an exotic matter field, in Rastall gravity, is calculated in an arbitrary d-dimensional spacetime. After this, we calculate t…
Thermodynamics of Black Holes in Rastall Gravity
Iarley P. Lobo, H. Moradpour, J. P. Morais Graça +1
A promising theory in modifying general relativity by violating the ordinary energy-momentum conservation law in curved spacetime is the Rastall theory of gravity. In this theory,…
Non-Abelian cosmic string in the Starobinsky model of gravity
J. P. Morais Graça, A. de Pádua Santos, Eugênio R. Bezerra de Mello +1
In this paper, we analyze numerically the behaviour of the solutions corresponding to a non-Abelian cosmic string in the framework of the Starobinsky model, i.e. where $f(R)=R + ζR…
Cloud of strings in f(R) gravity
J. P. Morais Graça, Iarley P. Lobo, I. G. Salako
We derive the solution for a spherically symmetric string cloud configuration in a d-dimensional spacetime in the framework of f(R) theories of gravity. We also analyze some thermo…
