Nonconservative traceless type gravity
Mahamadou Daouda, J. C. Fabris, A. M. Oliveira +2
Extensions of the gravity theory in order to obtain traceless field equations have been widely considered in the literature. The leading example of such class of theories is the un…
Non-trivial static, spherically symmetric vacuum solution in a non-conservative theory of gravity
A. M. Oliveira, H. E. S. Velten, J. C. Fabris
We analyse the vacuum static spherically symmetric space-time for a specific class of non-conservative theories of gravity based on the Rastall's theory. We obtain a new vacuum sol…
A Rastall Scalar-Tensor theory
T. Caramês, M. H. Daouda J. C. Fabris, A. M. Oliveira +2
We formulate a theory combining the principles of a scalar-tensor gravity and the Rastall proposal of a violation of the usual conservation laws. In the resulting Brans-Dicke-Rasta…
Newtonian View of General Relativistic Stars
A. M. Oliveira, H. E. S. Velten, J. C. Fabris +1
Although general relativistic cosmological solutions, even in the presence of pressure, can be mimicked by using neo-Newtonian hydrodynamics, it is not clear whether there exists t…
Gravitational lenses in the dark Universe
R. C. Freitas, S. V. B. Gonçalves, A. M. Oliveira
We discuss how different cosmological models of the Universe affect the probability that a background source has multiple images related by an angular distance of the line of…
