Phantom energy dominated universe as a transient stage in cosmology
P. H. R. S. Moraes, P. K. Sahoo, Barkha Taori +1
The theories of gravity are the most popular, simple and well succeeded extension of Einstein's General Relativity. They can account for some observational issues of standar…
The importance of scalar fields as extradimensional metric components in Kaluza-Klein models
P. H. R. S. Moraes, R. A. C. Correa
Extradimensional models are achieving their highest popularity nowadays, among other reasons, because they can plausible explain some standard cosmology issues, such as the cosmolo…
Cosmology from a running vacuum model driven by a scalar field
J. R. L. Santos, P. H. R. S. Moraes
The possibility that the vacuum energy density is, indeed, varying in time, has been investigated lately from the running vacuum models perspective. Motivated by such models,…
Compact Astrophysical Objects in gravity
P. H. R. S. Moraes, J. D. V. Arbañil, G. A. Carvalho +4
In this article we study the hydrostatic equilibrium configuration of neutron stars (NSs) and strange stars (SSs), whose fluid pressure is computed from the equations of state $p=ω…
Energy nonconservation as a link between gravity and noncommutative quantum theory
Ronaldo V. Lobato, G. A. Carvalho, A. G. Martins +1
gravity was proposed as an extension of the theories, containing not just geometrical correction terms to the General Relativity equations, but also material correc…
A conservative energy-momentum tensor in the gravity and its implications for the phenomenology of neutron stars
S. I. dos Santos, G. A. Carvalho, P. H. R. S. Moraes +1
The solutions for the Tolmann-Oppenheimer-Volkoff (TOV) equation bring valuable informations about the macroscopical features of compact astrophysical objects as neutron stars. The…
